As Samael Aun Weor explained in Igneous Rose, a Master of the Fourth or Fifth Initiation of Major Mysteries can raise the Kundalini, very slowly, through the terrific power of solar brahmacharya, abstention of sexual magic while possessing the solar bodies.
This is only for Masters with a solar mental body, not for individuals who have not created the Mercaba or solar vehicles and who do not have the sacred fire within them, which can only be generated in sexual alchemy, a perfect matrimony.
Those who do not have the Kundalini of the physical, vital, astral, and mental bodies awakened through sexual magic cannot raise the fire alone. Therefore, if celibate individuals filled with lust do not want to get burned by their lust, they must find a spouse to practice sexual magic.
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
