Dealing with Vital
Once the vital being has come forward and shown its difficulty—there is nobody who has not one crucial difficulty or another there—it must be dealt with and conquered.
It must be dealt with not by the mind but directly by the supramental power.
Not peace and knowledge in the mind, but peace, faith, calm strength in the vital being itself (and especially in this part of it that is defective) is the thing to be established. To open yourself and allow all this to be brought down into it is the proper course.
The deficiency is not in the higher mind or mind proper; there is therefore no use in going back to establish mental peace. The difficulty is in that part of the vital being which is not sufficiently open and confident and not sufficiently strong and courageous and in the physical mind which lends its support to these things. To get the supramental light and calm and strength and intensity down there is what you need.
You may have all the mental knowledge in the world and yet be impotent to face vital difficulties. Courage, faith, sincerity towards the Light, rejection of opposite suggestions and adverse voices are there the true help. Then only can knowledge itself be at all effective.
Not mental control but some descent of a control from above the mind is the power demanded in the realisation. This control derived eventually from the supermind is a control by the Divine Power.
