There is no miraculous force and I do not deal in miracles. The word Divine here is out of place, if it is taken as an always omnipotently acting Power. Yogic Force is then better; it simply means a higher Consciousness using its power, a spiritual and supraphysical force acting on the physical world directly. One has to train the instrument to be a channel of this force; it works also according to a certain law and under certain conditions. The Divine does not work arbitrarily or as a thaumaturge; He acts upon the world along the lines that have been fixed by the nature and purpose of the world we live in – by an increasing action of the thing that has to manifest, not by a sudden change or disregard of all the conditions of the work to be done. If it were not so, there would be no need of Yoga or time or human action or instruments or of a Master and disciples or of a Descent or anything else. It could simply be a matter for the [tath ¯ astu] and nothing more. But that would be irrational if you like and worse than irrational, – childish. This does not mean that interventions, things apparently miraculous, do not happen – they do. But all cannot be like that.
