As soon as there is torrents of rain, Vṛndāvana was going to be overflooded, Kṛṣṇa immediately came to their rescue and lifted the Govardhana Hill: "Come under Me." That is Gopī-jana-vallabha. They do not know anything. They do not know even that Kṛṣṇa is the Supreme Personality of Godhead. But they do not like to love anybody than Kṛṣṇa. This is their only qualification. They did not love Kṛṣṇa understanding that Kṛṣṇa is the Supreme Personality of Godhead, paraṁ brahma paraṁ dhāma (BG 10.12). They did not know this. But they did not like to love even Viṣṇu than Kṛṣṇa. That is their qualification. Gopī-jana-vallabha.
So when we come to that stage, as Caitanya Mahāprabhu's teaching, the gopī-bhartuḥ pada-kamalayoḥ . . . He's also bringing the reference of the gopī because Kṛṣṇa is completely under gopīs. He's so much indebted to the gopīs that He said that "I cannot repay your debts. It is not possible." Kṛṣṇa, the all-powerful, all opulences, but He had no means to repay the debts of the gopīs. This is the position of the gopīs. Caitanya Mahāprabhu recommends, ramyā kācid upāsanā vraja-vadhū-vargeṇa yā kalpitā (Caitanya-manjusa). There is no other better shape of worshiping Kṛṣṇa than it was planned by the gopīs. Ramyā kācid upāsanā vraja-vadhū-vargeṇa yā kalpitā. This is the highest. In the same way, He says, gopī-bhartuḥ pada-kamalayor dāsa, Gopī-jana-vallabha. Gopī-jana-vallabha is Kṛṣṇa; pada-kamalayoḥ, one who has taken shelter. Don't try to become gopīs. No. Rather, try to become the dust of the lotus feet of the gopīs.
