PURPORT
Here, the term ‘time’ denotes a path, having many deities beginning with day and ending with year. The deities preside over divisions of time.The meaning is—I declare to you the path departing in which Yogins do not return and also the path departing in which the doers of good actions return. By the clause, ‘Light in the form of fire, the day, bright fortinight, six months of the northern course,’ year also is denoted.
