The (Origin and Evolution of the) Universe is Self.

It is correct to note that the origin of the universe is self; or, to be more precise; 'the universe is self' for there is no separation whatsoever. We can replace the word self with I for all is one without a second (hence 'I am That I am'). The answer to the question as to why self gave birth to itself is out of the desire to love and be loved. Love is the essence of self's own physical beingness; this beingness that is life is love in truth. In conclusion: Life is love and blissfulness is the mechanism for love to manifest itself. It is why it is said that self is love and love is self for 'love self-exists'.
