The door of the Truth is covered by a golden disc. Open it, O Nourisher! Remove it so that I who have been worshipping the Truth may behold It.
Yajur Veda, Isa Upanishad, Part 1, Chapter 1, 15
O Nourisher, lone Traveller of the sky! Controller! O Sun, Offspring of Prajapati! Gather Your rays; withdraw Your light. I would see, through Your grace, that form of Yours which is the fairest. I am indeed He, that Purusha, who dwells there.
Yajur Veda, Isa Upanishad, Part 1, Chapter 1, 16
Now may my breath return to the all-pervading, immortal Prana! May this body be burnt to ashes! Om. O mind, remember, remember all that I have done.
Yajur Veda, Isa Upanishad, Part 1, Chapter 1, 17
