Series 1, Chapter 21 pg 220, Para 1: it its developed power of life, desire, emotion, passion, pleasure, suffering, while sattwa, emerging, but still dependent on the lower action, contributes to these the first light of the conscious mind, the mechanical sense of ego, conscious memory, a certain kind of thought, especially the wonders of instinct and animal intuition. But as yet the buddhi, the intelligent will, has not developed the full light of consciousness; therefore, no responsibility can be attributed to the animal for its actions. The tiger can be no more blamed for killing and devouring than the atom for its blind movements, the fire for burning and consuming or the storm for its destructions. If it could answer the question, the tiger would indeed say, like man, that it had free will, it would have the egoism of the doer, it would say, “I kill, I devour”; but we can see clearly enough that it is not really the tiger, but Nature in the tiger that kills, it is Nature in the tiger that devours; and if it refrains from killing or devouring, it is from satiety, from fear or from indolence, from another principle of Nature in it, from the action of the guna called tamas. As it was Nature in the animal that killed, so it is Nature in the animal that refrained from killing. Whatever soul is in it, sanctions passively the action of Nature, is as much passive in its passion and activity as in its indolence or inaction. The animal like the atom acts according to the mechanism of its Nature, and not otherwise, sadrsam cestate svasyah prakrteh, as if mounted on a machine, yantrarudho mayaya.
