Srimad Bhagvata Mahapurana: Book 10: Chapter 39: Verses 31-44
Sri Suka went on : Talking (to one another) in this strain and sore afflicted at the thought of separation, the women of Vraja-whose mind was deeply attached to Sri Krsna-cried loudly, casting all bashfulness to the winds, "0 Protector of cows, 0 Krsna (who was tied at the waist with a string by mother Yasoda), 0 Scion of Madhu !" In spite of the womenfolk (of Vraja) wailing as aforesaid, now that the sun had risen, Akrura-who had (just) finished his (Sandhya) prayers to the sun-god and other devotions-presently drove his chariot (in the direction of Mathura). The Gopas headed by Nanda thereupon closely followed him in their bullock-carts taking (with them) abundant presents including pitchers full of the yield of cows (in the shape of milk, curds and ghee). The cowherd women too followed their beloved Sri Krsna (to a short distance) and delighted (to some extent by His turning round and casting loving glances at them) they paused (awhile) awaiting the Lord's message in reply to theirs (which had evidently been sent by them through some special messenger). Observing them suffering agony as aforesaid at His departure, Sri Krsna (the foremost of the Yadus) comforted them with messages full of love, sent through a messenger, saying "I shall come (back)!" As long as the flag (of Sri Krsna's chariot) was visible and so long as the dust raised by the chariot continued to be seen, the Gopis-who had sent their mind after the Lord-were seen (standing) like so many painted figures. Hopeless of Govinda's return, they (all) retraced their steps and, rid of grief (by His loving assurances) passed their days and nights celebrating in songs the pastimes of their beloved Lord.
