Advaita Vedanta is a scientifically proven fact. Being Brahman is perfect Truth-accommodation. You are Brahman but confused because you are attached to your lower self, the body-brain-mind complex. There is no duality in Brahman, the ultimate and permanent Reality.
When you know that you are Brahman in its non-duality you are the incarnation of peace because you see Brahman in everyone and everything.
Brahmavid Brahmaiva bhavati: he who knows Brahman verily becomes Brahman (Upanishad).
