Self Love is (the essence of) Self.

It is a mad man indeed that names a disorder (Narcissism) after a flower (Narcissus) this while, in the process of doing so, overlooks the very essence of his own existency. Does existence itself not rely on Self-Love for it itself to exist? After all, is Self Love not the origin of Self? And is thus the denial of Self not ultimately the root cause of most Self-caused suffering in this world? To thine own Self be true; Love Self, Love All, All One!
