Although from the Vedic literature we can understand that there are similar forms in other parts of the world, at present there is no information of their location.
These forms of Kṛṣṇa are distributed throughout the world and throughout the universes to give pleasure to the devotees. It is not that devotees are born only in India. There are devotees in all parts of the world, but they have simply forgotten their identity. These forms incarnate not only to give pleasure to the devotees but to reestablish devotional service and perform other activities which vitally concern the Supreme Personality of Godhead. Some of these forms are incarnations mentioned in the scriptures, such as the Viṣṇu incarnation, Trivikrama incarnation, Nṛsiṁha incarnation and Vāmana incarnation.
