Srila Bhaktisiddhanta Sarasvati Thakura points out that in Vrajabhumi there is the Yamuna River with its sandy banks. There are kadamba trees, cows, Krsna's sticks with which He herds cows, and Krsna's flute. All of these belong to the santa-rasa, the mellow of neutrality in devotional service. There are also the direct servants of Krsna, such as Citraka, Patraka and Raktaka, and these are the embodiments of service in the mellow of servitude. There are also friends like Sridama and Sudama who embody service in fraternity. Nanda Maharaja and mother Yasoda are the embodiments of paternal love. Above all of these are Srimati Radharani and Her assistants, the gopis Lalita, Visakha and others, who embody conjugal love. In this way all five mellows-santa, dasya, sakhya, vatsalya and madhurya-exist eternally in Vrajabhumi. They are compared respectively to copper, bell metal, silver, gold and touchstone, the basis of all metals. Srila Kaviraja Gosvami therefore refers to a mine eternally existing in Vrndavana, Vrajabhumi.
