The book presents a psychological and spiritual justification for the self-determination of a person's life and his mission. Man is not just a mortal biopsychosocial being, he is an immortal consciousness of soul and spirit. The individual comes to Earth with a very specific mission, which he builds long before incarnation into a material body. In earthly life, he follows internal self-determination, influencing the laws of nature and society. In addition to the mission, he follows a flexible program of life, which, with the appropriate effort of consciousness, can significantly change for the better.
