God illumines the mind and shines within it. One cannot know God by means of the mind. One can but turn the mind inwards and merge it in God.
When the mind is left without anything to cling to, it becomes still.
Grace is ever present. All that is necessary is that you surrender to it.
Your true nature is that of infinite spirit. The feeling of limitation is the work of the mind.
Let what comes come, let what goes go.
Surrender is to give oneself up to the original cause of one's being.
