“According to the revelations of revealed scripture, Vṛndāvana extends only sixteen krośas [thirty-two miles]. Nonetheless, all the Vaikuṇṭha planets and innumerable universes are located in one corner of this tract.

In Vraja, the land is divided into various vanas, or forests. The forests total twelve, and their extension is estimated to be eighty-four krośas. Of these, the special forest known as Vṛndāvana is located from the present municipal city of Vṛndāvana to the village called Nanda-grāma. This distance is sixteen krośas (thirty-two miles).
