The higher Truth is all the time working in us but through the lower power - Aparashakti. It is when we become conscious of the play of this higher Power then only yoga begins.
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.
In the normal play of our mind there are all sorts of perversions; hence the need to stop all these things and inculcate right thinking, right willing - in other words, Truth must be established.
I swore that I would not suffer from the world's grief and the world's stupidity and cruelty and injustice and I made my heart as hard in endurance as the nether millstone and my mind as a polished surface of steel. I no longer suffered, but enjoyment had passed away from me.
The ascent to the divine Life is the human journey, the Work of works, the acceptable Sacrifice. This alone is man's real business in the world and the justification of his existence, without which he would only be an insect crawling among the ephemeral insects on a speck of surface mud and water which has managed to form itself amid the appalling immensities of the physical universe.
The first and the most important thing is to know that life is one and immortal. Only the forms, countless in number, are transient and brittle. The life everlasting is independent of any form but manifests itself in all forms. Life then does not die... but the forms are dissolved.
After having stopped the lower activities of the mind, it must be made receptive; and, instead of weaving all kinds of empty and idle thoughts, the mind should receive intuitions from above.
Indian religion has always felt that since the minds, the temperaments and the intellectual affinities of men are unlimited in their variety, a perfect liberty of thought and of worship must be allowed to the individual in his approach to the Infinite.
