That Supreme Light which projected Itself as the universe like a soaked seed which sprouts – I am that Supreme Light. I am that Supreme Light of Brahman which shines as the inmost essence of all that exists. In reality, I am the same Infinite Brahman even when I am experiencing myself as a finite self owing to ignorance. Now by the onset of knowledge (I realise that) I am really that Brahman, and That is my eternal nature. Therefore, I realise this identity by making myself, the finite self, an oblation into the fire of the Infinite Brahman, which I am always. May this oblation be well made.
~Mahanarayana Upanishad (I:67) of the Krishna Yajurveda
