From the Chinese 體 ti, which literally means “substance, body” and is often translated as “essence,” to indicate that which is always there throughout transformations. In gnosis, the term essence refers to our consciousness, which remains fundamentally the same, in spite of the many transformations it suffers, especially life, death, and being trapped in psychological defects. A common example given in Buddhism is a glass of water: even if filled with dirt and impurities, the water is still there. However, one would not want to drink it that way. Just so with the Essence (the consciousness): our Essence is trapped in impurities; to use it properly, it must be cleaned first.
