What is ThetaHealing® ?
The ThetaHealing® technique is a meditation technique utilizing a spiritual philosophy developed by Viana Stibal, owner of THInK & Let's THInK Unique. The technique uses low-frequency theta brain waves (slowed down to a frequency of 4 to 7 hertz) that correspond to brain frequencies before deep sleep. The main thing that theta treatments allow us to do is to change the state of our subconscious. Theta state of consciousness opens the door to the subconscious and from there we can perceive and remove all limiting beliefs, fears, and traumas, which hinder us from living the life we want. These can be beliefs and programs left to us by our parents or ancestors, or acquired at birth. Using the theta technique, we learn how to make the subconscious be our friend, not work against us, our happiness, health, success, and abundance that we want and deserve.
Our emotions are a product of our thoughts and beliefs, the way we experience the world around us. Those emotions produce chemical reactions in every cell and send us information about health or disease. Theta technique allows us to quickly and easily remove our fears, shame, shame, feelings of guilt, or remorse, feelings of loss, regret, anger, and hatred... and to transform them into joy, love, happiness, acceptance, and forgiveness, gratitude, health, and abundance.
Viana Stibal, the founder of this technique, believes that healing using theta brain waves is a very old method practiced by ancient peoples and civilizations.
ThetaHealing® and Science
"Today, science proves that 90 percent of all information in our brain is in our subconscious. It controls breathing, work, heart, and every function of the organism, It stores our memories and emotions, fears, trauma, anger, and sadness, which often manifest as physical psychosomatic illnesses. This is what psychoneuroimmunology, a new scientific discipline that proves that every thought and emotion in us produces a chemical reaction that carries information, deals with. Information is bought and transmitted by message carriers, neuropeptides, which are also found on the cell walls of our immune system, and not only in the brain as was believed until recently. When it receives information, our immune system sends a response in the form of illness or health.”

ThetaHealing® Session
Everything takes place through a conversation between the therapist and the client. Through talking about what a person wants to change in life, and what is troubling or worrying him at that moment, his deep convictions, blockages, often traumas, and fears are brought to his attention. Once conscious, these blockages are easily and quickly released with the help of a theta practitioner therapist. During the treatment, the client is aware and awake and generally perceives the session as a relaxing and liberating process. The theta therapist is trained to keep the theta brain waves awake and in contact with the client, so the client soon establishes theta waves. The practitioner asks questions that may seem strange at times, but it is important to answer them honestly because these answers come directly from the subconscious. It is necessary for the client to actively participate, although sometimes he may be upset, or angry, he may even cry, but this is short-lived. When the therapist, by asking deeper and deeper questions, gets to the fundamental beliefs of the client, he needs a little time to change them and remove the cause of the problem.
Seminars
At the seminars, participants get the basic knowledge about the ThetaHealing® technique and how to apply it independently.
At the basic seminar, you learn meditation and relaxation techniques, how to look at the reasons for everything that happens in a person's life, as well as how to adapt your reactions to those events. By acquiring these skills and knowledge, participants will be able to help themselves and others. These are mostly people who are on the path to self-knowledge and are ready to take responsibility for creating their own lives.
Are There Any Limitations and Conditions to ThetaHealing® ?
ThetaHealing® is not limited by age, race, gender, religion, or anything else. It respects every nationality, religion, and concept of God. It is a model of energy healing, a meditative process that heals on all levels of our being - physical, emotional, mental and spiritual. Anyone who has pure faith in God or Creator Energy can access and use this method. ThetaHealing® has much more to do with quantum physics than medicine, it is quantum physics in practice and hence all technically educated people accept it very easily. This technique has elements of yoga, reiki, prana or chi energy and shamanism. Prior knowledge of these spiritual techniques is helpful, but by no means necessary.
Jelena, Scientist and ThetaHealing® Instructor
"She was awarded for cancer detection software, and she focused her interests and creativity on the fields of consciousness development and spirituality.
Following the example of Nikola Tesla, Professor Dr. Jelena Vasiljević managed to combine the two sciences - of electrical engineering and medicine, and she proved her success in this in 2012 when she invented software for the early detection of a primary tumor, which later developed into metastases. The project has attracted a lot of attention from experts in the field of medicine. Application of the software facilitates the work of pathologists, and with newer versions of the software, radiologists as well, establishing diagnosis more quickly and reliably when detecting primary cancer. She inherited her talent for natural sciences from her father, who was also an inventor. When he died of metastases, not knowing that he had cancer, she decided to dedicate herself to researching the possibility of treating this disease.

HEALING WITH THETA WAVES
Working in science, Jelena directed her interests and creativity towards research in the field of consciousness and spiritual development. Wanting to help, first of all, herself, and then others, she began to study psychology, as well as the application of the ThetaHealing® technique.
- It all started when my father passed away. Mom and older sister had a hard time accepting it, but I reversed it to the order of love and, as the youngest, took on a lot of responsibility. On the one hand, taking care of the family, on the other, studying. Then the inflation started, the bombing, in general, it was very difficult and I needed a lot of inner strength to cope with the difficulties that befell me - says Jelena.
With the help of professional psychology literature, she tried to learn how to influence herself or, at least, her reaction to what happened to her. In addition to psychological, there were also physical manifestations, and after applying various methods, such as the Silva method, emotional freedom technique (EFT), and reiki, ThetaHealing® followed.
The whole philosophy of this teaching has a lot of similarities with the old teachings, where we turn to some universal energy, in the desire to learn something as if we were in school. In order to train others, it is necessary to complete a very interesting, but also quite demanding, seminar for instructors. There is always something good in every evil, and, in fact, the trials we go through should be understood as lessons that should teach us something and improve us as a person. That's how I worked hard and ended up becoming an instructor, right in the inconvenient time of the pandemic. Since then, I have helped many people, and I am especially pleased to help young people solve their problems, whether they are problems with studying, taking an exam with an awkward professor, nervousness, various phobias, creative blocks, love problems, relationship with parents or something else. Someone hear about what I do through friends, others through social networks, others come out of curiosity, but everyone has a common desire to understand the deep causes of their problems through theta technique and thus overcome them."

Testimonials and Recommendations
SANJA
“My experience was very special and profound. From the very beginning, I felt seen and accepted, because Jelena approached each of us with genuine care and warmth.
The course of the workshop felt light and natural, and even moments of confusion led me to important inner insights and an understanding of things I would never have become aware of on my own.
Through techniques and conversation, Jelena gently guided me to look at situations from different perspectives, which helped me recognize inner blocks and shift some deeply rooted beliefs.
By the end of the workshop, I felt fulfilled, calm, and deeply grateful to have been part of this process.”
Kristina Jašić
“I want to share my experience with the Theta Healing method that I experienced through a seminar and sessions with Jelena Vasiljević, as it deeply moved me and changed my perspective on many things. I attended the seminar with Jelena with the desire to free myself from stress, anxiety, and negative thoughts that constantly followed me. Jelena immediately created a safe and relaxed environment, which allowed me to fully relax and open up to the process.
The Theta Healing technique helped me recognize deeply rooted fears and blockages that I wasn’t even aware of having. Every exercise during the seminar was an opportunity to release old beliefs that were holding me back, and I felt how I was gradually becoming lighter and calmer. Although I didn’t immediately notice physical changes, my emotions and thoughts became much more positive, which over time led to significant improvements in my life.
One of the greatest benefits I noticed is that I no longer dwell on negative thoughts, and I find it easier to let go of things that hurt me. Sometimes it takes more sessions to achieve greater progress, but with each encounter, I felt I was getting closer to my inner peace.
If you are open to introspection and want to free yourself from limiting beliefs, I sincerely recommend Jelena Vasiljević. This process has helped me become a better version of myself and connect with myself on a deeper level.”

“I reached a point in my life where I had everything that is outwardly called success. But inside – there was a silence that wasn’t peace.
I was tired. Not from work, but from the person I had become. I had achieved a lot, yet felt very little. I knew that if I didn’t change something, I would lose myself.
I was searching for meaning, not comfort. I came across Theta Healing, which intrigued me as an approach, but it was important for me to learn from someone I could trust on a rational and academic level. I decided to call Jelena. An engineer, professor, and PhD – I knew I could trust her 
We worked intensively, the entire weekend.
At first, everything felt unusual, and then the “click” happened. It was as if spaces within me opened up – spaces I didn’t know I had the right to access.
That experience didn’t stay at the seminar. I carried it into my life and continued exploring further – quantum physics, neuroscience, neuroplasticity. The combination of science and inner work became my new strength.
Today, I am a different person – calmer, happier, more fulfilled. My values have changed. What matters to me now is that I am well, that my loved ones are well, and that I live in alignment with myself – happy in my own skin, fulfilled.
First, I changed.
And only then did my life change.
Thank you, Jelena – for the knowledge and for the space where I could remember who I am.”
JELENA POPOVIĆ – ELEN
“After my impressions settled, I felt the need to share my experience from the Basic Theta Healing seminar with Dr. Jelena Vasiljević, a certified Theta Healing instructor.
Honestly, I am extremely satisfied with the training.
For a long time, I had been searching for someone I could learn from and truly trust. A few months ago, I came across Jelena’s profile and intuitively felt that she was the right person.
I patiently waited for the training dates, and when I finally applied, it happened naturally, at just the right moment.
Since I already come from the world of esotericism, her approach resonated with me deeply. Even though I had prior knowledge, this seminar opened up new perspectives and gave me a broader, deeper understanding. During the training, I resolved many personal issues that had long been in the background, and my perception expanded significantly. Today, I connect things much more clearly, both on a personal and professional level.
I gained concrete and practical knowledge that I can apply immediately, which was truly exciting for me.
Working with Jelena and our interaction gave me additional confidence, as well as strong motivation to continue my education in this direction.
I am grateful for her simple, clear, and warm approach, as well as her genuine dedication.
It is truly a pleasure to meet someone who shares knowledge with such care and integrity.
I look forward to continuing our collaboration and to future meetings.”
Tamara Stanković
She told me, “Every student finds their teacher,” and from the very first day, I felt that it was true. Jelena, my teacher, showed me that healing pain, trauma, and negative emotions is possible with ease. She showed me that “without struggle, there IS learning,” and that everything in our reality can be changed. She passed on all the skills and knowledge to me, even more than that. I am very grateful for a teacher like Jelena. Thank you for your dedication, attention to detail, love for spiritual work, and healing. A big thank you, and I look forward to our continued collaboration!

“Jelena Vasiljević is a wonderful person… who opened the doors to my inner subconscious world. After the first treatment, everything started to flow into my life in a relaxed and spontaneous way… I trusted her… that everything would gradually fall into place. After the basic seminar, it felt like doors opened for beautiful events in my life. I had much better communication with people… colleagues… and also with men. A better door to my life has opened. Thank you, Jelena, for everything.”

Vesna Petrović
Dear Jelena,
Thank you for inviting me to the course, it was wonderful. Your dedication, warmth, the way you treat participants is something that is rarely seen. I am grateful to you for all the lessons and insights. Everything is so fast and easy with your guidance. Thanks to you, I was able to find the cause of the problem that had been bothering me for years.
Mirjana Zdravković
My first encounter with Theta healing therapy was with Jelena Vasiljević almost 10 years ago. My experience is that it is an extremely effective and powerful method of quickly “digging” to the root cause of a problem or situation. Especially when it is working with an experienced and talented therapist like Jelena, because with her in one session you do the topic from beginning to end, and that’s the end of it. There is no “hanging out” every week and exhausting psychotherapeutic conversations. Fast, efficient, effective. It changes life for the better. I recommend that you definitely try it. At one point I wanted to educate myself and become a Theta healing therapist myself. Jelena Vasiljević also guided me through that experience. The work in the seminars (Basic and Advanced) is deep, you work on your own beliefs and it is useful even if you do not want to work with others. Recommended for all those who want to work on themselves and have the opportunity to help others.
Irena Bulatović
I’m not someone who writes comments. I don’t know why, I want to praise, to say that I agree, but it always remains only in my head. I’m thinking whether I’m going to write nicely, whether I’m going to be extensive and boring, and then, and then, the wonderful soul Jelena Vasiljević enters my life. Let’s do the session as a conversation between two long-time friends and… I feel the need, I want to express my feelings, my happiness, my gratitude. That beautiful soul, the Theta Practitioner, soared me into an even greater happiness, gratitude than the one I lived every day, believing that It was It. Now I know that I can always do more and that’s all thanks to the selfless love that Jelena Vasiljević gave me. She is my revelation, God’s gift and Thank you Thank you Thank you 
. Just one meeting with her led to my expansion, the realization of my desires, my manifestation. Thanks to Jelena, I feel that I live abundantly. Dear souls, I want you to feel this way too, to help yourself in working with Jelena. I believe that you will get more than you expected. Now I signed up for all those silences.
With love to all of you.
Sanja Lazarević

Jasmina Dimitrijević
I have been attending ThetaHealing® sessions for more than 4 years. Theta transformed my personality in a wonderful and gentle way and opened the door to a new world. When I was ready for a new step in spiritual development, Jelena Vasiljević appeared and became my ThetaHealing® teacher.
She wove her pedagogic and expert professional knowledge in a wonderful and easy way into teaching and thus joined two worlds, material and spiritual. Jelena radiates gentleness and warmth, joy and support, beauty and knowledge. She is committed to her students, who remain so even after the training is over. I am grateful because you lead me on this wonderful path of bliss and grace.

…in medias res…
…one of the greatest skills in life is to make real friends, true and trusted companions…
…as well as to find people who show you the right path, teach and guide you, so you just follow them with a light but reliable step…
… and if they also carry light within themselves then everything is there, don’t worry…
This is how I experienced Jelena, my Theta teacher, a teacher with a capital T, during these two days of my Theta seminar.
Jelena, thank you!
Sara Dragović
Jelena is an excellent teacher, she pays maximum attention to all her students, helping them to practice ThetaHealing® the best possible. She selflessly shares her knowledge and explains everything in detail. She creates a special energy in the entire space with which the Theta state is achieved with ease.
I have fulfilled the goal I set for myself at the workshop. I use theta daily, during meditations, to solve all doubts and problems, as well as to instantly relieve stress and calm down. I am grateful for everything I have learned!
