Vedas teach that the soul is divine, only held in the bondage of matter; perfection will be reached when this bond will burst, and the word they use for it is therefore, Mukti — freedom, freedom from the bonds of imperfection, freedom from death and misery.
And this bondage can only fall off through the mercy of God, and this mercy comes on the pure. So purity is the condition of His mercy. How does that mercy act? He reveals Himself to the pure heart; the pure and the stainless see God, yea, even in this life; then and then only all the crookedness of the heart is made straight. Then all doubt ceases. He is no more the freak of a terrible law of causation. This is the very centre, the very vital conception of Hinduism. The Hindu does not want to live upon words and theories. If there are existences beyond the ordinary sensuous existence, he wants to come face to face with them.
If there is a soul in him which is not matter, if there is an all-merciful universal Soul, he will go to Him direct. He must see Him, and that alone can destroy all doubts. So the best proof a Hindu sage gives about the soul, about God, is: “I have seen the soul; I have seen God.” And that is the only condition of perfection. The Hindu religion does not consist in struggles and attempts to believe a certain doctrine or dogma, but in realising — not in believing, but in being and becoming. (I, 12-13)
As different from other religions, God’s grace reveals itself by making the seeker’s mind more and more pure so that the light of the Self within shines better and better. It lifts human mind to a universal level, eradicating dualistic ideas and feelings,opening up doors to the realisation of Self. God’s grace hastens this process of progress towards spiritual perfection. God’s grace is never meant for acquiring material benefits.
