Śaṅkarācārya's commentary

This Yoga, treated of in the two preceding Discourses, I taught to the Sun (Vivasvat) at the commencement of Evolution in order to infuse strength into the kṣatriyas, the rulers of the world. It is only when possessed of the strength of this Yoga that they can protect the brāhmaṇas, the spiritual class. And when the spiritual and ruling classes are well maintained, it is possible to maintain the world. That Yoga is imperishable, because of its imperishable results. Indeed, mokṣa, the fruit of this Yoga of complete devotion to right knowledge, never perishes. Vivasvat taught it to Manu; and Manu taught it to his son Ikṣvāku the first ruler.
