Three occult things are important for occult development: the lamp of Hermes Trismegistos with three flames, the thrice folded mantle of Apollonius, the staff of the masters that's divided into three parts.
The three flames through which one must become familiar with the teachings are thinking, feeling and willing (get into teachings with thinking and feeling and don't just do will exercises).
The mantle is the skin that one is supposed to leave. Stepping out is the second folding of the mantle and turning back towards the body is the third one. Tripartite staff.
