yat-prekṣaṇe dṛśiṣu pakṣma-kṛtaṁ śapanti
dṛgbhir hṛdī-kṛtam alaṁ parirabhya sarvās
tad-bhāvam āpur api nitya-yujāṁ durāpam
According to Śrīla Viśvanātha Cakravartī, just then Lord Balarāma saw the gopīs standing a short distance away. Seeing them trembling with eagerness to meet Kṛṣṇa, and apparently ready to give up their lives if they could not, He tactfully decided to get up and involve Himself elsewhere. Then the gopīs attained the state described in the current verse. In referring to the gopīs’ intolerant disrespect of Lord Brahmā, “the creator of eyelids,” Śukadeva Gosvāmī is giving vent to his own subtle jealousy of the gopīs’ favored position.
Śrīla Jīva Gosvāmī offers an alternate understanding of the phrase nitya-yujām, which may mean “even of the Lord’s principal queens, who tend to be proud of their constant association with Him.”
In Kṛṣṇa, the Supreme Personality of Godhead, Śrīla Prabhupāda writes: “Because they had been separated from Kṛṣṇa for so many years, the gopīs, having come along with Nanda Mahārāja and mother Yaśodā, felt intense ecstasy in seeing Kṛṣṇa. No one can even imagine how anxious the gopīs were to see Kṛṣṇa again. As soon as Kṛṣṇa became visible to them, they took Him inside their hearts through their eyes and embraced Him to their full satisfaction. Even though they were embracing Kṛṣṇa only mentally, they became so ecstatic and overwhelmed with joy that for the time being they completely forgot themselves. The ecstatic trance which they achieved simply by mentally embracing Kṛṣṇa is impossible to achieve even for great yogīs constantly engaged in meditation on the Supreme Personality of Godhead. Kṛṣṇa could understand that the gopīs were rapt in ecstasy by embracing Him in their minds, and therefore, since He is present in everyone’s heart, He also reciprocated the embracing from within.”
