This little separate self must die. Then we shall find that we are in the Real, and that Real is God, and He is our own true nature, and He is always in us and with us. Let us live in Him and stand in Him. It is the only joyful state of existence. Life on the plane of the Spirit is the only life, and let us all try to attain to this realization.
Swami VivekanandaThe body is the external coating and the mind is the internal coating of the Atman who is the real perceiver, the real enjoyer, the being in the body who is working the body by means of the internal organ or the mind.
Swami VivekanandaFirst get rid of the delusion "I am the body," then only will we want real knowledge.
Swami VivekanandaFirst, meditation should be of a negative nature. Think away everything. Analyse everything that comes in the mind by the sheer action of the will. Next, assert what we really are-existence, knowledge, and bliss-being, knowing, and loving.
Swami Vivekananda
