This inconscience is no more real than the ignorance of exclusive concentration in our temporary being which limits the waking consciousness of man; for as in us, so in the atom, the metal, the plant, in every form of material Nature, in every energy of material Nature, there is, we know, a secret soul, a secret will, a secret intelligence at work, other than the mute self-oblivious form, the Conscient, — conscient even in unconscious things, — of the Upanishad, without whose presence and informing Conscious-Force or Tapas no work of Nature could be done.” The Life Divine

“Every man is knowingly or unknowingly the instrument of a universal Power and, apart from the inner Presence, there is no such essential difference between one action and another, one kind of instrumentation and another as would warrant the folly of an egoistic pride. The difference between knowledge and ignorance is a grace of the Spirit; the breath of divine Power blows where it lists and fills today one and tomorrow another with the word or the puissance. If the potter shapes one pot more perfectly than another, the merit lies not in the vessel but the maker. The attitude of our mind must not be ‘This is my strength’ or ‘Behold God’s power in me’, but rather ‘A Divine Power works in this mind and body and it is the same that works in all men and in the animal, in the plant and in the metal, in conscious and living things and in things apparently inconscient and inanimate.’” The Synthesis of Yoga
