Separation of the Inner Purusha When the inner being once thoroughly establishes its separateness, even oceans of inertia cannot prevent it from keeping it. It is the first thing to be done in order to have a secure basis in the yoga, to establish thoroughly this separateness. It comes most usually when the peace is thoroughly fixed in the inner parts, then the separateness also becomes fixed and permanent. *   ...when there is the peace and the mental silence, the vital mind tries to rush in and occupy the place or else the mechanical mind tries to raise up for the same purpose its round of trivial habitual thoughts. What the sadhak has to do is to be careful to reject and hush these outsiders, so that during the meditation at least the peace and quietude of the mind and vital may be complete. This can be done best if you keep a strong and silent will. That will is the will of the Purusha behind the mind; when the mind is at peace, when it is silent one can become aware of the Purusha, silent also, separate from the action of the nature.       To be calm, steady, fixed in the spirit, dhira, sthira, this quietude of the mind, this separation of the inner Purusha from the outer Prakriti is very helpful, almost indispensable. So long as the being is subject to the whirl of thoughts or the turmoil of the vital movements, one cannot be thus calm and fixed in the spirit. To detach oneself, to stand back from them, to feel them separate from oneself is indispensable.
