“We must become so alone, so utterly alone, that we withdraw into our innermost self. It is a way of bitter suffering. But then our solitude is overcome, we are no longer alone, for we find that our innermost self is the spirit, that it is God, the indivisible. And suddenly we find ourselves in the midst of the world, yet undisturbed by its multiplicity, for our innermost soul we know ourselves to be one with all being.”
