These are explained in the Bhāgavatam, Uddhava explained to Vidura that Kṛṣṇa is so kind, God is so kind, even the person who wanted to kill Him with poison, she was accepted as mother. Such a kind God, Kṛṣṇa, that "Whom shall I worship others, except Kṛṣṇa?" This example is given. So actually Kṛṣṇa has no enemy. Here it is said: na yasya kaścid dayitaḥ. Dayitaḥ means favor. Nobody is favored. Na yasya kaścid dayito 'sti karhicid dveṣyaś ca. And nobody is His enemy. But who can be His enemy, who can be His friend?
Suppose we create friends. We expect some benediction or some profit from the friend and enemy means we expect some harmful activities by the enemy. But Kṛṣṇa is so perfect that nobody can do any harm to Kṛṣṇa, neither anybody can give anything to Kṛṣṇa. So where is the necessity of friend and enemy? There is no necessity. Therefore it is stated here: na yasya kaścid dayito 'sti. He doesn't require anyone's favor. He's complete. I may be very poor man. I expect some friend's favor, somebody's favor. But that is my expectation because I am perfect. I am not full. I am deficient in so many ways. So I am in needy always. Therefore I want to create some friend, and similarly I hate the enemy. So Kṛṣṇa, His being the Supreme nobody can do any harm to Kṛṣṇa, nobody can give anything to Kṛṣṇa. So why we are offering Kṛṣṇa so much comforts? We are dressing Kṛṣṇa, we are decorating Kṛṣṇa, we are giving nice food to Kṛṣṇa.
