In every man and in every animal, however weak or wicked, great or small, resides the same omnipresent, omniscient soul. The difference is not in the soul, but in the manifestation. Between me and the smallest animal, the difference is only in manifestation, but as a principle he is the same as I am, he is my brother, he has the same soul as I have. This is the greatest principle that India has preached.
Swami Vivekananda
