Since everything emanates from God, he is the embodied principle in every being. Each one of us is made from God. Tat twam asi - "You are That One" who is eternally blissful, that one principle manifesting itself as this variety of Creation.
Swami VivekanandaNot even the deepest sleep will give you such a rest as meditation can. The mind goes on jumping even in deepest sleep. Just those few moments in meditation your brain has almost stopped. ... You forget the body. ... You feel such pleasure in it. You become so light. This perfect rest we will get in meditation.
Swami VivekanandaYou cannot take away one atom of matter or one foot-pound of force. You cannot add to the universe one atom of matter or one foot-pound of force. As such, evolution does not come out of zero; then, where does it come from? From previous involution.
Swami VivekanandaAy! says the Vedanta, it is not the fault of God that this partiality exists, that this competition exists. Who makes it? We ourselves. There is a cloud shedding its rain on all fields alike. But it is only the field that is well cultivated, which gets the advantage of the shower; another field, which has not been tilled or taken care of cannot get that advantage. It is not the fault of the cloud.
Swami Vivekananda
