Three things to shorten Difficulty

There are three things you can do to alleviate and shorten the difficulty:

1) Detach yourself from this vital-physical—observe it as something not yourself; reject it, refuse your consent to its claims and impulses, but quietly as the witness Purusha whose refusal of sanction must ultimately prevail. This ought not to be difficult for you, if you have already learned to live more and more in the impersonal Self.

2) When you are not in this impersonality, still use your mental will and its power of assent or refusal,—not with a painful struggle, but in the same way, quietly, denying the claims of desire, till these claims by loss of sanction and assent lose their force of return and become more and more faint and external.

3) If you become aware of the Divine above you or in your heart, call for help, for light and power from there to change the vital itself, and at the same time insist upon this vital till it itself learns to pray for the change.
