In plain words
To Kaṃsa, who thought Him no God but an enemy, He took the form of Yama. To Hiraṇyakaśipu, who said, ‘There is no God’, who never thought of the Name of Hari, and who hated Him, He turned into Yama. To Prahlāda, who thought of Nārāyaṇa without ceasing, ‘Nārāyaṇa bhaja Nārāyaṇ Nārāyaṇ bhaja Nārāyaṇ Nārāyaṇ Nārāyaṇ’, He appeared as God. To Rāvaṇa, who bore hatred for Rāma and made ready to fight with Rāma, He turned into Yama. To Vibhīṣaṇa, who held Rāma to be his all and came to Him in Śaraṇāgati, He appeared as God. So Yama and God are not two; they are one! It is each one's own feelings that went on appearing as Yama or as God.
The Bhāgavatam Means the Story of God!
Kṛṣṇa went on appearing to all as God. One day all the Gopīs were very weary. Every day, as He played such pranks, they would go chasing after Kṛṣṇa. Then He went on giving them the teaching of Jñāna. ‘Alas, poor things! They are pure of citta, free of selfishness, innocent Gopīs. I keep slipping away from them. This time I must surely let them catch Me. I must be bound by them. I am one who is in the hands of My devotees. For one such as Me to trouble the devotees is not good,’ He resolved. All the Gopīs marked the time when Kṛṣṇa would come. They all stood like soldiers, to find out how He would get away. He poured all the milk in the hanging pot down onto the floor. He came along wetting both His feet in that milk. Seeing this sight, they all came chasing after Him. Nobody knew where He had run. At last, taking the print of those feet as their guide, they went searching, ‘Where is Kṛṣṇa?’ Then the light of Jñāna dawned on them. ‘Gopīs! Take refuge at My feet. Then I shall be caught by you. Follow My feet, and I shall be caught’: to give this teaching He wet His feet in the milk and went along, printing them clearly as He went. The principle of God described in the Bhāgavatam is laughable only to those who take it as laughable!
