It was believed in ancient Egypt that the orgasm was the key to eternal life, and that it was intimately connected with the chakra system.
A chakra is an energy vortex connected to the entire human energy field, and the Universal Heart Chakra is the fifth of thirteen chakras. (There is also a system of eight chakras; in that system, the heart chakra is number four.)
The Egyptian system held that the orgasm was intimately connected to this fifth, or Universal Heart Chakra.
