Translation
The Absolute Truth is the objective of devotional sacrifice, and it is indicated by the word sat. The performer of such sacrifice is also called sat, as are all works of sacrifice, penance and charity which, true to the absolute nature, are performed to please the Supreme Person, O son of Pṛthā.
