तं नागभोगपरिवीतमद‍ृष्टचेष्ट-मालोक्य तत्प्रियसखा: पशुपा भृशार्ता: ।कृष्णेऽर्पितात्मसुहृदर्थकलत्रकामादु:खानुशोकभयमूढधियो निपेतु: ॥ १० ॥

ITRANS:

taṁ nāga-bhoga-parivītam adṛṣṭa-ceṣṭamālokya tat-priya-sakhāḥ paśupā bhṛśārtāḥkṛṣṇe ’rpitātma-suhṛd-artha-kalatra-kāmāduḥkhānuśoka-bhaya-mūḍha-dhiyo nipetuḥ

Translation:

When the members of the cowherd community, who had accepted Kṛṣṇa as their dearmost friend, saw Him enveloped in the snake’s coils, motionless, they were greatly disturbed. They had offered Kṛṣṇa everything — their very selves, their families, their wealth, wives and all pleasures. At the sight of the Lord in the clutches of the Kāliya snake, their intelligence became deranged by grief, lamentation and fear, and thus they fell to the ground.

Purport:

Śrīla Sanātana Gosvāmī explains that the cowherd boys, along with some cowherd men and farmers who happened to be in the vicinity and who were also devotees of Kṛṣṇa, fell to the ground just like trees that had been cut at the root.
