Krishna's apparent partiality is an illusion; He distributes mercy equally like the sun shares light to all.Listen — Srila Prabhupada Uvaca
Śrīmad-Bhāgavatam 1.8.29 — October 9, 1974, Māyāpur 741009SB-MAYAPUR [28:54 Minutes] SB-01.08.29_741009SB-MAYAPUR Nitāi: "O Lord, no one can understand Your transcendental pastimes, which appear to be human and are so misleading. You have no specific object of favor, nor do You have any object of envy. People only imagine that You are partial." Prabhupāda: na veda kaścid bhagavaṁś cikīrṣitaṁ tavehamānasya nṛṇāṁ viḍambanam na yasya kaścid dayito 'sti karhicid dveṣyaś ca yasmin viṣamā matir nṛṇām [SB 1.8.29] So Kuntīdevī is clarifying the matter that people may think that Kṛṣṇa was partial to the Pāṇḍava family and He was envious to the Kurus because He always took part on behalf of the Pāṇḍavas. That has been described.
So just like worldly men, we, we make some friends and we make some enemies. To somebody we are envious, and to somebody we are very friendly. This is material nature. The material nature means to become envious, generally.
And if somebody satisfies my sense gratification, then he's friend. That is also temporary. As soon as the sense gratification process is disturbed, then again envious. The real nature is enviousness.
So Kuntīdevī says that "Because You are playing the part of human being, and it appears that You are partial to somebody and You are envious to somebody, this is viḍambanam; this is Your misleading. Actually You are not like that. Actual... But because You are playing the part of the ordinary human being—not ordinary, but as human being—so Your dealing like that appears that You are, to some..., to somebody You are very partial and somebody You are inimical." But that is not the fact.
People cannot understand Kṛṣṇa because Kṛṣṇa can be understood by the devotee only. nāhaṁ prakāśaḥ sarvasya yogamāyā-samāvṛtaḥ mūḍho 'yaṁ nābhijānāti mām eva param avyayam [Bg. 7.25] Those who are mūḍhas, they cannot understand Kṛṣṇa. Kṛṣṇa is playing, although like that, ordinary human being, the mūḍhas cannot understand. Just like Kṛṣṇa killed Pūtanā, but she got elevation to the position of His mother. Superficially it appeared that Kṛṣṇa killed the Pūtanā, but Pūtanā, Kṛṣṇa took her as her [His] mother.
Although she came to kill Kṛṣṇa with poison on her breast, but Kṛṣṇa thought that "This woman has come to kill Me, but because I have sucked her breast, she is My mother." So any way, the service side, Kṛṣṇa always accepts, a little service. Therefore in the Bhagavad-gītā it is said, svalpam apy asya dharmasya trāyate mahato bhayāt. Svalpam asya. A little service to Kṛṣṇa is feasible, is helpful, to save a man from the greatest danger. So further she explains, na yasya kaścid dayitaḥ.
Dayita means favorable. Na yasya kaścid dayitaḥ asti karhicid dveṣyaś ca yasmin. And nobody is envious. The Bhagavad-gītā also confirms, samo 'haṁ sarva bhūteṣu na me dveṣyo 'sti kiñcana [Bg. 9.29].
