The Truth-power must be brought down from above into that state of peace, and this higher power - Parashakti - will directly guide the vehicle - ādhāra - and transform it.
Yes, this Purusha consciousness must be maintained; otherwise the calm will not last. The knocks and blows that come from outside cannot disturb one, if this Purusha consciousness remains at the back.
What do you want to do sadhana for? The aim should not be the satisfaction of egoism: "I want to be a great yogi; I shall have so much power and with that power I shall establish myself in the world." All such thoughts must be thrown far away.
Faith is the soul's witness to something not yet manifested, achieved or realised, but which yet the Knower within us, even in the absence of all indications, feels to be true or supremely worth following or achieving.
The supramental transformation, the supramental evolution must carry with it a lifting of mind, life and body out of themselves into a greater way of being in which yet their own ways and powers would be, not suppressed or abolished, but perfected and fulfilled by the self-exceeding.
Not only a truer knowledge, but a greater power comes to one in the quietude and silence of a mind that, instead of bubbling on the surface, can go to its own depths and listen.
The yoga we practice is not for ourselves alone, but for the Divine; its aim is to work out the will of the Divine in the world, to effect a spiritual transformation and to bring down a divine nature and a divine life into the mental, vital and physical nature and life of humanity. Its object is not personal Mukti, although Mukti is a necessary condition of the yoga, but the liberation and transformation of the human being. It is not personal Ananda, but the bringing down of the divine Ananda - Christ's kingdom of heaven, our Satyayuga - upon the earth.
For the powers of our mind, life, and body are bound to their own limitations, and however high they may rise or however widely expand, they cannot rise beyond them. But still, mental man can open to what is beyond him and call down a Supramental Light, Truth, and Power to work in him and do what the mind cannot do. If mind cannot by effort become what is beyond mind, Supermind can descend and transform mind into its own substance.
You carry in yourself all the obstacles necessary to make your realization perfect. If you discover a very black hole, a thick shadow, be sure there is somewhere in you a great light. It is up to you to know how to use the one to realize the other.
All religions have some truth in them, but none has the whole truth; all are created in time and finally decline and perish. Mahomed himself never pretended that the Koran was the last message of God and there would be no other. God and Truth outlast these religions and manifest themselves anew in whatever way or form the Divine Wisdom chooses.
