Prabhupada's lecture - Śrīmad-Bhāgavatam 1.8.32 - Māyāpura, October 12, 1974
Therefore here it is said that priyasya, yadoḥ priyasya. King Yadu became very dear to Kṛṣṇa by rendering service. Priyasya. The... As Kṛṣṇa is very dear to the devotee, similarly, devotees are also very, very dear to Kṛṣṇa. There is another verse, sva-pāda-mūlaṁ bhajataḥ priyasya. Sva-pāda-mūlaṁ bhajataḥ priyasya: "If one is engaged at the lotus feet of Kṛṣṇa, he becomes very, very dear." Sva-pāda-mūlaṁ bhajataḥ priyasya. Bhajataḥ, one who is simply engaged for rendering service to the lotus feet of Kṛṣṇa—he has no other business—he becomes priya. And as soon as you become priya, or dear to Kṛṣṇa, then your all problems solved.
Just like if you become a dear child of a very big, rich man, then where is your problem? Automatically he's taken care of. Because he has become dear child of a very big man, so what is his problem? No problem. Similarly, we have to become very dear to Kṛṣṇa. Then all our problems solved.
