Since we are 97% ego, it does not take much to go over the edge.

If you learn to awaken your consciousness, discriminate your internal and external environments, and protect yourself from potential dangers, you will perceive that more and more people are awakening negatively with greater ease, consistency, and pervasiveness than one wants to admit.

Most spiritual movements teach people how to crystallize consciousness within desire. This occurs by learning to integrate and intensify the ego by mixing mysticism with lust.

Samael Aun Weor compared it to taking a handful of snow and compacting it into a ball. Where before the ego was scattered, separate, and fragmented, such desires become compounded into a negative or sinister psychological center of gravity when combining sexual energy with self-will.

Most spiritual books at any bookstore will teach you how to strengthen desire through concentration upon lust. It's not complicated, but easy, which is why more people are doing so at an exponential rate.
