Swami Vivekananda on Divine Mother

The Divine Mother is the power of all causation. She energizes every
cause unmistakably to produce the effect. Her will is the only law,
and as She cannot make a mistake, nature's laws--Her will--can never
be changed. She is the life of the law of karma, or causation. She is
the fructifier of every action. Under Her guidance we are
manufacturing our lives through our deeds or karma.

From notes discovered among Swami Vivekananda's papers. He evidently
intended to write a book and jotted down these points for the work.
