"My dear King," the Lord said, "because you are a kṣatriya, you have committed the offense of slaughtering animals, both in hunting and in political engagements. To become purified, just engage yourself in the practice of bhakti-yoga and always keep your mind absorbed in Me. Very soon you will be freed from all reactions to such sordid activities." In this statement it appears that although kṣatriyas are allowed to kill animals in hunting, they are not freed from the resultant contamination of sinful reactions. Therefore, whether one is a kṣatriya, vaiśya or brāhmaṇa, everyone is recommended to take sannyāsa at the end of life, to engage himself completely in the service of the Lord and thus become freed from all sinful reactions of his past life.
The Lord then assured King Mucukunda, "In your next life you will take your birth as a first-class Vaiṣṇava, the best of brāhmaṇas, and in that life your only business will be to engage yourself in My transcendental service." A Vaiṣṇava is a first-class brāhmaṇa because one who has not acquired the qualification of a bona fide brāhmaṇa cannot come to the platform of a Vaiṣṇava. When one becomes a Vaiṣṇava, he is completely engaged in welfare activities for all living entities. The highest welfare activity for living entities is the preaching of Kṛṣṇa consciousness. It is stated herein that those who are specifically favored by the Lord can become absolutely Kṛṣṇa conscious and be engaged in the work of preaching the Vaiṣṇava philosophy.
