After Kaṁsa killed the ṣaḍ-garbhas, the six sons of Devakī, one after another, Anantadeva entered Devakī’s womb and was transferred to the womb of Rohiṇī by the manipulation of Yoga-māyā, who was following the order of the Supreme Personality of Godhead. The Lord Himself, who was soon to appear as the eighth son of Devakī, ordered Yoga-māyā to take birth from the womb of Yaśodādevī. Because Kṛṣṇa and His potency, Yoga-māyā, appeared simultaneously as brother and sister, the world is full of Vaiṣṇavas and śāktas, and there is certainly some rivalry between them. Vaiṣṇavas worship the Supreme Lord, whereas śāktas, according to their desires, worship Yoga-māyā in forms like Durgā, Bhadrakālī and Caṇḍikā. Following the orders of the Supreme Personality of Godhead, Yoga-māyā transferred Baladeva, Saṅkarṣaṇa, the seventh child of Devakī, from the womb of Devakī to the womb of Rohiṇī. Because Saṅkarṣaṇa appears in order to increase love of Kṛṣṇa, He is known as Baladeva. One may take auspicious strength from Him to become a devotee of the Lord, and therefore He is also known as Balabhadra.
