Temptation is [sexual] fire. The triumph over temptation is light. -Samael Aun Weor, The Great Rebellion
Even the gods, the resurrected masters who manifest in this world, have bodies that take on the masculine or feminine sex to continue working.
However, many of them, like Zanoni and Samael Aun Weor, have fallen in love and consummated the sexual act when it was forbidden to them.
In synthesis, the danger of falling is always present until one enters the Ain: the Unmanifested Absolute, the final liberation.
