Initiates in Egypt descended for years into hidden chambers within the pyramids, to the “Other World”, where they studied and practiced higher energy work.
Among their practices were:
- Transmuting
- Rite of the Sepulchre - where they would abide in a transcendental state bathed in oil - beyond death, for the purpose of renewal
- Study, scribing.
- Slowing down the breath.
- Mastering the art of Perpetual Youth.
- Kundalini energy work
- Psychic Abilities

These were all rightful use of energy - not Egoic.
