Katyayani Vrata.
All the unmarried gopīs in Vṛndāvana used to daily worship goddess Kātyāyanī early in the morning after taking a bath in the river Yamunā. Kātyāyanī is another name for goddess Durgā.
The goddess is worshiped by preparing a doll made of sand from the bank of the Yamunā. The gopīs used to prepare the deity of goddess Durgā and worship it with candana pulp, garlands, incense, lamps and all kinds of presentations—fruits, grain and twigs of plants.
The unmarried girls used to pray with great devotion to goddess Kātyāyanī, addressing her as follows: “O supreme external energy of the Personality of Godhead, O supreme mystic power, O supreme controller of this material world, O goddess, please be kind to us and arrange for our marriage with the son of Nanda Mahārāja, Kṛṣṇa.”

Beautiful traditional decorations by local expert craftsmen from the holy dham of Nabadwip. Definitely some locals having too much fun…
