“ ‘All the gopīs assembled to chant the transcendental qualities of Kṛṣṇa very loudly, and they began to wander from one forest to another like madwomen. They began to inquire about the Lord, who is situated in all living entities, internally and externally. Indeed, they even asked all the plants and vegetables about Him, the Supreme Person.’ ”
This is a quotation from Śrīmad-Bhāgavatam (10.30.4). The gopīs almost went mad due to Kṛṣṇa’s suddenly leaving the rāsa dance. Because the gopīs were fully absorbed in thoughts of Kṛṣṇa, they were imitating His different postures and pastimes. They became very much saddened because of His absence, and this incident is explained by Śukadeva Gosvāmī to Mahārāja Parīkṣit.
