It seemeth to us, however, that thou art possessed of intelligence and self-control in consequence of acquaintance with the scriptures. It, therefore, behoveth thee to discourse to us in magnanimous words fraught with learning.” The mendicant Rishi answered, “Ye immortals, it hath been heard by me that by untying all the knots in the heart by the aid of tranquillity, and by mastery over all the passions, and observance of true religion, one should regard both the agreeable and the disagreeable like his own self.

In plain words: The Sadhyas say he seems wise and self-controlled from studying the scriptures, and they ask him to teach them. The sage answers that a person should untie the knots in the heart through calm and self-control. Then that person can treat pleasant and unpleasant things the same way they treat themselves.
