The "Song of the Free", a classic text of Advaita Vedanta expresses the highest experience of the unfettered Self. Sanskrit text, transliteration and English translation. One of the purest statements of the supreme knowledge of Advaita, by a sage who lived over three thousand years ago.
As soon as I think that I am a little body, I want to preserve it, to protect it, to keep it nice, at the expense of other bodies; then you and I become separate.
-Swami Vivekananda
