The Supreme Lord said: O emperor, great ruler, your mind is pure and potent. Though I enticed You with benedictions, your mind was not overcome by material desires. KB 10.51.58 On hearing this statement by King Mucukunda, Lord Kṛṣṇa replied, “My dear King, I am very much pleased with your statement. You have been the king of all the lands on this planet, but I am surprised to find that your mind is now freed from all material contamination. You are now fit to execute devotional service. I am most pleased to see that although I offered you the opportunity to ask from Me any kind of benediction, you did not take advantage of asking for material benefits. I can understand that your mind is now fixed in Me, and it is not disturbed by any material quality.” The material qualities are three, namely goodness, passion and ignorance. When one is placed into the mixed material qualities of passion and ignorance, various kinds of greed and lusty desires impel him to try to find comfort in this material world. When situated in the material quality of goodness, one tries to purify himself by performing various penances and austerities. When one reaches the platform of a real brāhmaṇa, he aspires to merge into the existence of the Lord. But when one desires only to render service unto the lotus feet of the Lord, he is transcendental to all these three qualities. The pure Kṛṣṇa conscious person is therefore always free from all material qualities.
