According to Vedic civilization, unmarried girls from ten to fourteen years of age are supposed to worship either Lord Śiva or the goddess Durgā in order to get a nice husband. But the unmarried girls of Vṛndāvana were already attracted by the beauty of Kṛṣṇa. They were, however, engaged in the worship of the goddess Durgā in the beginning of the hemanta season (just prior to the winter season). The first month of hemanta is called Agrahāyana (October-November), and at that time all the unmarried gopīs of Vṛndāvana began to worship goddess Durgā with a vow. They first ate haviṣyānna, a kind of foodstuff prepared by boiling together mung dahl and rice without any spices or turmeric. According to Vedic injunction, this kind of foodstuff is recommended to purify the body before one enacts a ritualistic ceremony. All the unmarried gopīs in Vṛndāvana used to daily worship goddess Kātyāyanī early in the morning after taking bath in the River Yamunā. Kātyāyanī is another name for goddess Durgā. The goddess is worshiped by preparing a doll made out of sand mixed with earth from the bank of the Yamunā. It is recommended in the Vedic scriptures that a deity may be made from different kinds of material elements; it can be painted, made of metal, made of jewels, made of wood, earth or stone or can be conceived within the heart of the worshiper. The Māyāvādī philosopher takes all these forms of the deity to be imaginary, but actually they are accepted in the Vedic literatures to be identical with either the Supreme Lord or a respective demigod.
