Synonyms
śrī-kaśyapaḥ uvāca — Kaśyapa Muni said; putraḥ — son; te — your; bhavitā — will be; bhadre — O gentle woman; indra-hā — killer of Indra, or follower of Indra; adeva-bāndhavaḥ — friend of the demons (or deva-bāndhavaḥ – friend of the demigods); saṁvatsaram — for a year; vratam — vow; idam — this; yadi — if; añjaḥ — properly; dhārayiṣyasi — you will execute.
Translation
Kaśyapa Muni said: My dear gentle wife, if you follow my instructions regarding this vow for at least one year, you will surely get a son who will be able to kill Indra. However, if you deviate from this vow of following the Vaiṣṇava principles, you will get a son who will be favorable to Indra.
Purport
The word indra-hā refers to an asura who is always eager to kill Indra. An enemy of Indra is naturally a friend to the asuras, but the word indra-hā also refers to one who follows Indra or who is obedient to him. When one becomes a devotee of Indra, he is certainly a friend to the demigods. Thus the words indra-hādeva-bāndhavaḥ are equivocal, for they say, “Your son will kill Indra, but he will be very friendly to the demigods.” If a person actually became a friend of the demigods, he certainly would not be able to kill Indra.
