Q: From your recent answers I now deduce that I have been misusing the terms “lower forces” and “hostile forces”. What exactly is the difference between the two?
There are natural movements of the ordinary human nature in the material consciousness which take time to get rid of. Of course we call them forces of the lower nature but one must not regard them as hostile, but only ordinary. They have to be changed but it usually takes time and it can be done quietly. One must be more occupied with the positive side of the sadhana than with them. If one is always thinking of them as hostile things, getting disturbed when they come, considering them as hostile possessions, then it is not good. The things that are really hostile are few and must be distinguished from the ordinary movements of the nature. The first must be repelled, the second dealt with quietly and without getting troubled or discouraged by their appearances.
