Tantric way of development
The "Tantric way of development” is constructed in such a way that the woman's body belongs to the man, and the man's body belongs to the woman. The man is responsible for the life and health of the woman, and the woman is responsible for the life and health of the man. The man must develop her lower, upper and pericardium energy centers. And the woman has to develop these three centers in him. These centers should develop harmoniously.
