If you LOVE not the life of the most minute bacteria, as you would LOVE your mother, brother, sister, father, lover, then you LOVE and care for their and your own life not at all, as without all creatures small, there would be no creatures great, that is how deeply dependent and interdependent human life is to all other life, but the truth is this we need all other life, more than all other life needs us; this a fact our highly evolved ego has deluded the our species to forget.
“A human being is a part of the whole called by us universe, a part limited in time and space. He experiences himself, his thoughts and feeling as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.” ~ Albert Einstein
