Atman is Self. Self is Love. Love Experiences Itself.

It is common knowledge that Brahman and Atman are two sides of the same coin. As such; Atman/Brahman experiences itself. The answer to the question as to what is Atman is Self. The answer to the question as to what is Self is Love. In conclusion: Love experiences itself, i.e., Tat Tvam Asi. In addition; there is no non-Self, there is no non-Love. Self itself exists; Love itself exists. It's all very simple really. Love, simply Love.  Love is One without a second. Verily all this is Love.
