The root of evil is in the illusion that we are bodies. This, if any, is the original sin.
Swami VivekanandaI am what I am, and what I am is always due to him; whatever in me or in my words is good and true and eternal came to me from his mouth, his heart, his soul. Sri Ramakrishna is the spring of this phase of the earth's religious life, of its impulses and activities. If I can show the world one glimpse of my Master, I shall not have lived in vain.
Swami VivekanandaThen from the world all spirituality will be extinct, all moral perfection will be extinct, all sweet-souled sympathy for religion will be extinct, all ideality will be extinct; and in its place will reign the duality of lust and luxury as the male and female deities, with money as its priest, fraud, force, and competition its ceremonies, and the human soul its sacrifice. Such a thing can never be.
Swami Vivekananda
