vyaktaṁ sṛjasy avasi lumpasi tad-guṇa-sthaḥ
naitair bhavān ajita karmabhir ajyate vai
yat sve sukhe ’vyavahite ’bhirato ’navadyaḥ
The word durvibhāvyam is significant here. The ultimate cause of the creation, maintenance and annihilation of the material world is certainly inconceivable even for the greatest mundane scientists, who waste their lives in useless and fruitless speculation. Yet Mahā-Viṣṇu, who is the secondary expansion of an expansion of the Supreme Lord, Kṛṣṇa, sees the entire cosmos to be like an insignificant atom. So what hope is there for foolish so-called scientists who try to understand Kṛṣṇa by their ridiculous experimental power? Thus the word anavadya is used. No one can find fault or discrepancy in the body, character, activities or instructions of the Supreme Personality of Godhead. The Lord is never materially ignorant; therefore He never exhibits cruelty, laziness, foolishness, blindness or material intoxication. Similarly, because the Lord is never polluted by material passion, He never exhibits material pride, lamentation, yearning or violence. And since the Lord is free from material goodness, He never attempts to peacefully enjoy the material world with a sublime materialistic mentality.
Lord Kṛṣṇa, as stated here (sve sukhe ’vyavahite ’bhirataḥ), is eternally busy, day and night, in His transcendental abode, relishing the inconceivable loving devotion of His innumerable associates. The Lord is being embraced and is embracing. He is joking and is hearing the joking of His loved ones. The Lord is walking through forests full of fruits and flowers, playing in the nectarean river Yamunā and taking part in His most confidential transcendental loving affairs with the cowherd girls of Vṛndāvana. These pastimes in Kṛṣṇaloka and on other Vaikuṇṭha planets are eternal, faultless and an ocean of spiritual happiness. The Lord never descends to the dry platform of relative material happiness. The infinite Personality of Godhead has nothing to gain from anyone; thus fruitive activity cannot possibly exist within the Lord.
