He experienced an extraordinary state of open consciousness. He said: "It was as if I recalled something I had known before and forgotten". He received two gifts. The gift of spirit - to know the truth of life law directly without learning and mediators, and the gift of healing. By the gift of spirit he elaborated the philosophy of Being and he also established biotronics as a healing discipline and soon became a healer, a biotronic - sanator of a world format. He demonstrated to doctors successful healings of the most serious illnesses and saved many people by masterful healing of cancer. Despite the disfavour of state ideology he was also successful abroad.
