Grieg, as his friends call him, was born on March 12, 1952, in Tărtășești, near Bucharest. From an early age, he felt a profound calling to know God, who revealed Himself to him as a living, grandiose, and eternal reality. This experience later transformed into an unstoppable aspiration, an intense preoccupation, and a benevolent willingness to help others discover Him as well.

His spiritual concerns, however, quickly brought him to the attention of the communist authorities.

Thus began years of terror and harassment by the Securitate.

Aware of the risks he was exposing himself to, Gregorian Bivolaru began teaching yoga in the early 1970s and continued to do so secretly, even when yoga, and even martial arts, were banned. He was arrested, imprisoned, and tortured. In response, Grieg escaped from Securitate custody, something that remained unique in the history of that macabre institution. He was then imprisoned again for… escaping.

In January 1990, he founded what would later become the largest yoga school in Europe: the Movement for Spiritual Integration into the Absolute – MISA.

It is especially significant that yoga teacher Gregorian Bivolaru continued to be regarded as a great “danger” by all the power structures that followed after communism, and later all of them continued, and even now continue, to operate in the same way. The explanation for all of this is simple: the spiritual teachings he offers with great selflessness and generosity are new and revolutionary. The vast majority of these fundamental esoteric teachings are a living expression of ancient, millennia-old spiritual doctrines that have always sought, and continue to seek, the rapid and decisive emancipation of the human being who is prepared for this, as well as the gradual and systematic fulfillment of their real, Godly purpose.

Despite all the very great and by no means negligible obstacles, Gregorian Bivolaru continued both his spiritual activity, guiding the development of the yoga school as a mentor, and his activity as a prolific author of many works on diverse spiritual themes.

To date, he has already published more than 150 books and brochures and has written hundreds of articles. The yoga course structured by him has expanded practically throughout Romania, as well as abroad, and includes more than 1,300 audio-video lessons and around 800 written courses. Also, some sister yoga schools have opened their doors in more than 30 countries on all continents.

His spiritual teachings have always had, and continue to have, an eminently practical aspect, addressing almost all the concerns of sincere, enthusiastic, and persevering aspirants. Such efficient modalities include methods for healing and maintaining optimal health, overcoming possible problems that arise in the psychic sphere, and attaining and deepening excellent states of mind; awakening and exploring genius and clearly superior creativity; and, for those engaged in an intense spiritual search, novel and ancient modalities and techniques belonging to the branches of yoga that aim at the fruitful discovery, through direct experience, of the answers to the fundamental questions of life: “Where do I truly come from?”, “Where am I heading in this existence?”, “Who am I truly, beyond appearances?”, “What is the true meaning of my life?”, “What will happen to me after the death of the body?” They concern the existence and the certain feeling of the existence of God; the revelation and deepening of the absolute essence of our being, the Supreme Immortal Self, Atman; the total replacement of sexuality, which is something inferior, with the clearly superior choice of lovemaking that includes amorous erotic continence, which confers great happiness and plenitude; the exploration of the prior consecration to God of the fruits of our important actions, which frees us from their subsequent karma-ic consequences; the extraordinary practical use of the more than 700 Godly Attributes that God revealed for the first time in this esoteric Spiritual School; the approach to advanced spiritual stages in yoga practice; and the living of a happy, balanced, and fulfilling existence.

In 2009, the Gregorian Bivolaru was initiated in the spiritual communities, with the name of the Movement, Charismatic, c. m., which has the motto: "In God is because God, in God, in God." The goal of this document is to help them in their quest for the spiritual aspirants honest, and who aspire to wake up the soul, and to find God in their inner world, as well as in everything that surrounds them.

In 2009, Gregorian Bivolaru initiated the spiritual community called the Theophanic Charismatic Movement, whose motto is: “With God, for God, in God, into God.” Its aim is to help sincere spiritual aspirants in their search — those who aspire to awaken their soul and discover God both in their inner universe and in everything that surrounds them.

Based on his direct practical experiences, Grieg has always explained all traditional, ancient techniques — some of which had been kept secret — from the perspective of modern man.

Gregorian Bivolaru has already achieved a unique, complex, creative, and above all practical synthesis of various authentic Eastern and Western spiritual traditions, most of which still remain cryptic and inaccessible to the Western world when they are not accompanied by clear and appropriate esoteric explanations — explanations that can arise only from immense personal spiritual experience.

He has also introduced over the years a series of ingenious and clearly revolutionary concepts and techniques, which are in reality based on universal Godly spiritual principles and which then transform, as if by magic, spiritual practice from something immense that often appears confusing and unknown to us into something very intelligible, accessible, and inspiring. When such ingenious methods are correctly put into practice, they clearly lead to major beneficial transformations in all areas of life.

One of Grieg’s greatest contributions to universal planetary spirituality, which already has many extraordinary implications that are only just beginning to come to light, is the formidable revelation of the Godly Attributes that the Good God offered him at the right moment. Through this unique Godly disclosure, which includes an inestimable value, each Godly Attribute appears to us through direct experience as an eternal, omnipresent, freely available sublime subtle energy, possessing a vibrational frequency that never changes. Examples of such Godly Attributes include Love, Goodness, Omnipotence, Eternity, Justice, Compassion, Pure Eros, Stenic Humor, Good, Beauty, Infinity, Happiness, Aspiration, Enthusiasm, Courage, Joy, Forgiveness, Patience, Altruism, Truth, Holiness, Faith, Sincerity, Omniscience, and Omnipresence. God gradually revealed to Gregorian Bivolaru, through Godly inspiration, more than 700 Godly Attributes and, for the first time in the world, disclosed to him the extraordinary secrets of the Meta Godly Attributes and those of the Mega Godly Attributes.

Being a markedly beneficially oriented personality, yoga teacher Gregorian Bivolaru has disturbed, and continues to disturb, some people through his revelations and actions inspired by God. At the same time, Gregorian Bivolaru has inspired many intelligent people in various astonishing ways. Those who thirst for authentic spirituality and who have already carefully and perseveringly put into practice his teachings and guidance, Gregorian Bivolaru has never ceased — and will never cease — to guide on the path toward perfection, with great humility and a permanent state of Godly relay. The revelation through him of the Mystery of the Godly Attributes is already proof that he is, and continues to remain, a living relay of God in this world.

Always, in almost all moments of his life, in all his teachings inspired by God, in his yoga courses, in the activity of the Theophanic Charismatic Movement that he created, in almost all his lectures, and in the countless audio-video discussions, sometimes filmed, with the students of the Yoga School and with his friends, both male and female, Gregorian Bivolaru has had, and continues to have almost without interruption, a central point of reference toward which everything is in fact directed and which simultaneously encompasses everything: this is the Infinite, Eternal, and Absolute Being of God the Father.
