Something small in the smaller vital.
If an adverse Force comes, one has not to accept and welcome its suggestions, but to turn to the Mother and refuse to turn away from her. Whether one can open or not, one has to be loyal and faithful. Loyalty and fidelity are not qualities for which one has to do yoga. They are very simple things which any man or woman who aspires to the Truth ought to be able to accomplish.
It is what everybody should realise. It is the psychic fidelity that brings the power to stand against the Asuras and enables the Protection to work.
You ask whether the adverse Force is stronger than the Divine Force. The implication is that man has no responsibility for his action and whatever he does or however he errs and falls in consequence, the Divine Force is to blame. It may be so, but in that case there is no need or utility in doing sadhana. One has only to sit still and let the adverse Force or the Divine Force do what they like! According to that theory the Devil was quite right in telling Christ, "Cast thyself down from this mountain and let His angels come and upbear thee," and Christ was quite wrong in rejecting the suggestion and saying, "It is written 'Thou shalt not tempt (put to a test) the Lord thy God!' " He ought to have jumped and if he got smashed, it would only have proved that the adverse forces were greater than the Divine Force!
