In plain words
In the same way there are many great men, yogīs, ṛṣis and all such people. If one asks who Vaśiṣṭha's brother is, you do not know. Agastya is Vaśiṣṭha's brother. If you come to know something of the lives of such people, you can purify your heart well and, through that, try to enter that path. Students cannot go up to so high a standard all at once. So, hoping and blessing you that you will understand something of the lives of the great, enter that path and reach the goal, I bring My discourse to a close.
