The mind is the instrument, the flywheel, and the thickest comrade of man. Through it, one can ruin oneself or save oneself. Regulated and controlled, channeled properly it can liberate; wayward and let loose, it can entangle and bind fast.
Come behold this world, which is like unto an ornamented royal chariot, wherein fools flounder, but for the wise there is no attachment.
This Self who gives rise to all works, all desires, all odours, all tastes, who pervades the universe, who is beyond words, who is joy abiding, who is ever present in my heart, is Brahmn indeed. To him I shall attain when my ego dies.
If you desire to be pure, have firm faith, and slowly go on with your devotional practices without wasting your energy in useless scriptural discussions and arguments.
