Kaśyapa Muni’s first instruction to his wife was not to be envious. The general tendency of anyone within this material world is to be envious, and therefore, to become a Kṛṣṇa conscious person, one must curb this tendency, as stated in Śrīmad-Bhāgavatam ( paramo nirmatsarāṇām ). A Kṛṣṇa conscious person is always nonenvious, whereas others are always envious. Thus Kaśyapa Muni’s instruction that his wife not be envious indicates that this is the first stage of advancement in Kṛṣṇa consciousness. Kaśyapa Muni desired to train his wife to be a Kṛṣṇa conscious person, for this would suffice to protect both her and Indra.
