It is not possible to make a fixed rule covering all cases and circumstances; sometimes one has to remain quiet waiting for the Mother’s light and force to act, sometimes it is necessary to use an active tapasya. But one thing is always necessary, to refuse to accept the adverse forces and suggestions that try to disorganise and disturb the system; for the basis of the Yoga must be peace, quiet, clarity, self-possession and nothing should be allowed to invade and upset the basis and substitute confusion and disorder.
