On a gnostic site, students are informed that egos deplete energy in the centres where the egos are fed. Thus, sexual energy is brought up from the base chakra to energise chakras higher up on the body. The energy at this root chakra is said to be the most powerful and superior to the energy in the other centres. A lack of energy there is said to lead to lust. Lust then contaminates new energy drawn to that centre. Also, energy pulled back from the higher centres is supposed to be contaminated.

Is this correct?
