Not only in this universe but in all other universes as well these forms of Kṛṣṇa are distributed everywhere. It is indicated that this earth is divided into seven islands, which are the seven continents, and it is understood that on every island there are similar forms. But at the present moment these are found only in India. 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.
In the Siddhārtha-saṁhitā there is a description of the twenty-four forms of Viṣṇu, and these forms are named according to the position of the symbols in Their four hands. When describing the positions of objects in the hands of the Viṣṇu mūrtis, one should begin with the lower right hand and then move to the upper right hand, to the upper left hand and finally to the lower left hand. In this way, Vāsudeva is represented by club, conch shell, disc and lotus flower. Saṅkarṣaṇa is represented by club, conch shell, lotus flower and disc. Similarly, Pradyumna is represented by disc, conch shell, club and lotus flower. Aniruddha is represented by disc, club, conch shell and lotus flower. In the spiritual sky the representations of Nārāyaṇa are twenty in number and are described as follows: Śrī Keśava (lotus, conch shell, disc and club), Nārāyaṇa (conch, lotus, club and disc), Śrī Mādhava (club, disc, conch and lotus), Śrī Govinda (disc, club, lotus and conch), Viṣṇu-mūrti (club, lotus, conch and disc), Madhusūdana (disc, conch, lotus and club), Trivikrama (lotus, club, disc and conch), Śrī Vāmana (conch, disc, club and lotus), Śrīdhara (lotus, disc, club and conch), Hṛṣīkeśa (club, disc, lotus and conch), Padmanābha (conch, lotus, disc and club), Dāmodara (lotus, disc, club and conch), Puruṣottama (disc, lotus, conch and club), Acyuta (club, lotus, disc and conch), Nṛsiṁha (disc, lotus, club and conch), Janārdana (lotus, disc, conch and club), Śrī Hari (conch, disc, lotus and club), Śrī Kṛṣṇa (conch, club, lotus and disc), Adhokṣaja (lotus, club, conch and disc), and Upendra (conch, club, disc and lotus).
According to the Hayaśīrṣa-pañcarātra, there are sixteen forms, and these are also named according to the positions of the disc and so on. The conclusion is that the Supreme Original Personality of Godhead is Kṛṣṇa. He is called līlā-puruṣottama, and He resides principally in Vṛndāvana as the son of Nanda. It is also learned from the Hayaśīrṣa-pañcarātra that there are nine forms protecting the two Purīs known as Mathurā Purī and Dvārakā Purī. These nine forms are Vāsudeva, Saṅkarṣaṇa, Pradyumna, Aniruddha, Nārāyaṇa, Nṛsiṁha, Hayagrīva, Varāha and Brahmā. These are different manifestations of the prakāśa and vilāsa forms of Lord Kṛṣṇa.
