SB 11.6.8
tvam mayaya tri-gunayatmani durvibhavyam
vyaktam srjasy avasi lumpasi tad-guna-sthah
naitair bhavan ajita karmabhir ajyate vai
yat sve sukhe ’vyavahite ’bhirato ’navadyah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O unconquerable Lord, You engage Your illusory energy, composed of three modes, to unleash, maintain and devastate the inconceivable manifest cosmos, all within Your own self. As the supreme superintendent of maya, You appear to be situated in the interaction of the modes of nature; however, You are never affected by material activities. In fact, You are directly engaged in Your own eternal, spiritual bliss, and thus You cannot be accused of any material infection.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The word durvibhavyam 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 Maha-Visnu, who is the secondary expansion of an expansion of the Supreme Lord, Krsna, sees the entire cosmos to be like an insignificant atom. So what hope is there for foolish so-called scientists who try to understand Krsna 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 Krsna, as stated here (sve sukhe ’vyavahite ’bhiratah), 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 Yamuna and taking part in His most confidential transcendental loving affairs with the cowherd girls of Vrndavana. These pastimes in Krsnaloka and on other Vaikuntha 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.
