Viparita Karani Mudra

It is evident that in order to achieve the three hours, a long time is necessary, maybe several years of constant practice, yet those years of constant practice are equivalent to defeating death by means of the famous Viparita Karani Mudra.

“The esoteric Viparita Karani teaches scientifically how the Hindu yogi, instead of ejaculating his semen, raises it slowly through concentration in such a way that a man and woman can eliminate the animal ego while united sexually. The esoteric Viparita Karani teaches how, through concentration, the “yogi slowly raises the semen, in such a way that
man and woman can attain Vajroli.”

As stated in the Viparita Karani: “This practice is the most excellent one, the cause of liberation for the yogi; this practice brings health to a yogi and grants him perfection.” - Samael Aun Weor, The Mystery of the Golden Blossom

"In India, the degree of culture is measured according to the time-span that the chemical copulation is endured. Whosoever endures three hours is respected and is a "lord." - Samael Aun Weor, The Revolution of the Dialectic

Somebody read this literally, did not understand, and thought that he had to practice three hours daily. Thus, he went to the Master, very proud, and asked, "Master, what do you think about working three hours in Sexual Magic?" because that is what he was doing.

Master Samael said to him, "Lust, lasciviousness, what else?"

"But what about the three hours?"

"Oh, well you are reading mechanically."

Three days. After three days and three nights, the Lord resurrects. First hour, the first mountain; second hour, the second mountain; third hour, the eight years of Job. Those are the three hours. Usually Initiates reach only the First hour; they reach Mastery, that is it. Rare are the ones who practice the second hour, and very rare are the ones that take the third hour. Three denials, three hours—it is a symbol. The time is a symbol. If you read everything mechanically, you do not know where you are going, and you start over-practicing. - Rune Perth
