H.P. Blavatsky (in a private talk with W.Q. Judge): "You force yourself into a Master's presence and you take the consequences of the immense forces around him playing on yourself. If you are weak in character anywhere, the Black Ones will use the disturbance by directing the forces engendered to that spot and may compass your ruin. It is so always. Pass the boundary that hedges in the occult realm, and quick forces, new ones, dreadful ones, must be met. Then if you are not strong you may become a wreck for that life. This is the danger. This is one reason why Masters do not appear and do not act directly very often, but nearly always by intermediate degrees."
