From sexual energy to spiritual energy (Ojas Shakti)
The sexual energy must be transmuted into spiritual energy or Ojas Shakti by the practice of Japa, prayer, meditation, study of religious books, Pranayama and Asanas. You must develop devotion and a burning desire for liberation. You must constantly meditate on the pure, immortal, sexless, bodiless, desireless Atman. Then only the sexual desire will be annihilated.
If the sexual energy is transmuted into Ojas or spiritual energy by pure thoughts, it is called sex sublimation in western psychology. Sublimation is not a matter of suppression or repression, but a positive, dynamic, conversion process. It is the process of controlling the sex energy, conserving it, then diverting it into higher channels, and finally, converting it into spiritual energy or Ojas Sakti.
The material energy is changed into spiritual energy, just as heat is changed into light and electricity. Just as a chemical substance is sublimated or purified by raising the substance through heat into vapour which again is condensed into solid form, so also, the sexual energy is purified and changed into divine energy by spiritual Sadhana.
Ojas is spiritual energy that is stored up in the brain.
By entertaining sublime, soul-elevating thoughts of the Self or Atman, by meditation, Japa, worship and Pranayama, the sexual energy can be transmuted into Ojas Sakti and stored up in the brain. This stored up energy can then be utilised for divine contemplation and spiritual pursuits.
