Sanskrit for this text is pending; the English follows the translator's numbering.
Om is the bow, the Self is the arrow. Brahman is called its aim. It is to be hit by a man who is not thoughtless; and then, as the arrow (becomes one with the target), he will become one with Brahman.
Translated by F. Max Müller
