"Be still, and know that I am God," sings the Biblical Psalmist. This simply means that the movement of thoughts and emotions is to be brought to an end by entering the deepest degree of contemplation. The same teaching is given in the Bhagavad Gita. "As the wick of an oil lamp placed in a wind-free spot is flickerless, so is the yogi of mastered mind who practises union with the God-Self."
