For it was by action alone that the ancients, the learned kṣatriyas, set out to reach perfection, liberation. Who? Janaka, Aśvapati and the rest. If they had attained the right vision, then they set out to reach perfection while still in action, without renouncing it, for the sake of holding the world together, since action had already begun for them. But if Janaka and the rest had not attained the right vision, then the verse must be explained as: they set out to reach perfection through action as the means to the purification of being, by stages. And if you think, 'the ancients too, Janaka and the rest, did the action to be done while still not knowing, so it need not necessarily be done by another, by one who has the right vision and is fulfilled', even so, bound by the action already begun, you ought to act, looking solely to the holding-together of the world, that holding-together being the prevention of the world's straying onto a wrong path. Why is the holding-together of the world to be done? He says.
