There cannot be two almighty beings in this world. [Imagine having] two or three Gods; one will create the world, another says, "I will destroy the world." It [can] never happen. There must be one God. The soul attains to perfection; [it becomes] almost omnipotent [and] omniscient. This is the worshipper. Who is the worshipped? He, the Lord God Himself, the Omnipresent, the Omniscient, and so on. And above all, He is Love. How is [the soul] to attain this perfection? By worship.
Swami VivekanandaMan makes the mistake of separating himself from God and identifying himself with the body.
Swami VivekanandaThe body and mind are continually changing, and are, in fact, only names of series of changeful phenomena, like rivers whose waters are in a constant state of flux, yet presenting the appearance of unbroken streams. Every particle in this body is continually changing; no one has the same body for many minutes together, and yet we think of it as the same body.
