realize the Divine

Why is concentration supercritical to realize the Divine?

You have to become Divine, the Divinity from which you have arrived. So lessen your attachment to the world, not by cutting yourself off from the world, but by being in it, as an instrument in His hands. To realize the omnipotent Divine within you, recognize your kinship with the Universe. Keep your body fit, light and bright. Don’t add to it the burden of attachment to this and that. Subdue the heads of all the tendencies within you that lead you to egoism. Have single-minded attention to the dictates of God and practice right-conduct. Edison, the great scientist concentrated so much on the solution of the problems that worried him that at times, he left food untouched for days on end, when they were pushed through the doors of his lab. You must have that same concentration and earnestness, when engaged in spiritual practices.
