Transmutation strengthens the consciousness so it can work against desire.
With sexual contact between husband and wife, the creative energy is turned into energetic steam that rises within the spinal medulla. Sperm and ova are transformed into energy, which, to use conventional language, is a form of death and rebirth, guided by the power of the couple’s love.
Discomfort in the sexual organs is overcome through pranayama, sexual transmutation, and comprehension in meditation.
Sexual energy degenerates through fornication in mind (sexual fantasy), body (orgasm), and soul (subtle lustful desires), not because of one’s underwear or an occasional sauna. If these latter things concern you, then the simple solution is to avoid them.
For thirty years I sought God. But when I looked carefully I found that in reality God was the seeker and I the sought. -Bayazid al-Bastami
