According to this philosophy, each man consists of three parts - the body, the internal organ or the mind, and behind that, what is called the Atman, the Self.
Swami VivekanandaโBlessed are the pure in heart, for they shall see God.โ This sentence alone would save mankind, if all books and prophets were lost. This purity of heart will bring the vision of God. It is the theme of the whole music of this universe. In purity is no bondage. Remove the veils of ignorance by purity; then we manifest ourselves as we really are and know that we were never in bondage. The seeing of 'many' is the great sin of all the world. See all as Self and love all; let all idea of separateness go.
Swami VivekanandaThe book one must read to learn natural sciences is the book of nature. The book from which to learn religion is your own mind and heart.
Swami VivekanandaWhenever power is used for evil, it becomes diabolical; it must be used for good only.
Swami VivekanandaThere 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 Vivekananda
