Even Lord Kṛṣṇa restricted His father, Nanda Mahārāja in worshiping the demigod Indra because He wanted to establish that people need not worship any other demigod except the Supreme Personality of Godhead. Because the ultimate aim of life is to return to the abode of the Supreme Lord. The abode of Lord Kṛṣṇa is described in the Bhagavad-gītā, 15th Chapter, 6th verse,
- na tad bhāsayate sūryo
- na śaśāṅko na pāvakaḥ
- yad gatvā na nivartante
- tad dhāma paramaṁ mama
Now the description of that eternal sky... When we speak of sky, because we have material conception of the sky, therefore we think of sky with sun, moon, stars, like that. But the Lord says that the eternal sky, there is no need of sun. Na tad bhāsayate sūryo na śaśāṅko na pāvakaḥ (BG 15.6). Neither in that eternal sky there is need of moon. Na pāvakaḥ means neither there is necessity of electricity or fire for illuminating because the spiritual sky is already illuminated by the brahma-jyotir.
