“As you turn inwards and penetrate more deeply into yourself, you will discover more and more your own emptiness, that you are not all that you are not, that you are not what you would wish to be, that you are, in a word, only a nonentity. And in touching your own nothingness, in not feeling your permanent base, in not reaching your own infinity, still less your own eternity, you will have a whole-hearted pity for yourself, and you will burn with a sorrowful love for yourself – a love that will consume your so-called self-love, which is merely a species of sensual self-delectation, the self-enjoyment, as it were, of the flesh of your soul.
Spiritual self-love, the pity that one feels for oneself, may perhaps be called egotism; but nothing could be more opposed to ordinary egoism. For this love or pity for yourself, this intense despair, bred of the consciousness that just as before you were born you were not, so after your death you will cease to be, will lead you to pity – that is, to love – all your fellows and brothers in this world of appearance, these unhappy shadows who pass from nothingness to nothingness, these sparks of consciousness which shine for a moment in the infinite and eternal darkness. […]
And thus you will come to pity all things; you will arrive at universal love.”
— Miguel de Unamuno – Tragic Sense of Life
