From an early age, a person thinks about who he is, why he is here. Later, in confusion, he thinks: “Why is there no happiness? What happened with me?". Sometimes a prosperous person in the prime of life falls into inexplicable melancholy. The whole world becomes unkind, nothing makes you happy, your soul literally hurts. Only love, caring for children and family sometimes saves women from the depression and emptiness that lurks. However, turning to religion is rarely successful. It is impossible to believe in “miracles” and fables that have come down to us from ancient times. Sincere faith must agree not only with feeling, but with reason and new knowledge. A new understanding of man, his goals and purpose in life is necessary. This will give everyone a spiritual foundation, intuitive faith and confidence. This is the only path to joy and happiness, and it is indicated in the book. Author: Dmitry Nikolaevich Taganov – Candidate of Sciences, Professor.
