This is Caitanya Mahāprabhu's teaching, that "From Kṛṣṇa's side, He may do whatever He likes"—that is full surrender—"still, He is my master. He's nobody else. He is still my worshipable master." Bhaktivinoda Ṭhākura has sung,
- mānasa deho geho jo kichu mor
- arpiluṅ tuwā pade nanda-kiśor
Nanda-kiśora is Kṛṣṇa. So this is full surrender. "My dear Nanda-kiśora, whatever I have got, now I am offering everything to You." What I have got? Mānasa deho geho: "I have got my body, I have got my mind, and a so-called home or a wife or a few children. What I have got? So everything is offered to You." Mānasa deho geho jo kichu mor. This is full surrender. Now he says, mārobi rākhobi jo icchā tohārā: "I am surrendering to You everything. Now if You like You can save me, or if You like You can kill me." This is full surrender.
So these Pāṇḍavas are the best example, and better than the Pāṇḍavas, there are other devotees. And the topmost surrendered devotee are the gopīs. There is no more higher exalted devotees than the gopīs. Therefore Caitanya Mahāprabhu recommended that the gopīs, ramyā kācid upāsanā vraja-vadhū-vargeṇa yā kalpitā (Caitanya-mata-mañjuṣā, quoted in Gauḍīya-kaṇṭhahāra 4.41). There is no better type of worshiping Kṛṣṇa than the method by which gopīs worship Kṛṣṇa. They, their love was so intense that they did not care for any family, any honor or any prestige—nothing. That is the highest, topmost loving stage of Kṛṣṇa. And Kṛṣṇa also loved the gopīs, so much so that Kṛṣṇa asked them that "You cannot expect any return from Me for your ecstatic love. I cannot give you. It is beyond My power." So they purchased Kṛṣṇa. And the topmost gopī is Rādhārāṇī. So we should not consider these gopīs' dealings with Kṛṣṇa as ordinary, material dealings. It is not that.
