This Kāmadeva, who appears as Kṛṣṇa’s son named Pradyumna, is viṣṇu-tattva. How this is so is explained by Madhvācārya, who quotes from the Brahmāṇḍa Purāṇa: kāmadeva-sthitaṁ viṣṇum upāste. Although this Kāmadeva is viṣṇu-tattva, His body is not spiritual but material. Lord Viṣṇu as Pradyumna or Kāmadeva accepts a material body, but He still acts spiritually. It does not make any difference whether He accepts a spiritual or a material body; He can act spiritually in any condition of existence. Māyāvādī philosophers regard even Lord Kṛṣṇa’s body as material, but their opinions cannot impede the spiritual activity of the Lord.
