Some of the chief devotees, such as Akrura, stayed with Kamsa to satisfy him. This they did for various purposes. They all expected the Supreme Personality of Godhead to appear as the eighth child as soon as Devakis other children were killed by Kamsa, and they were eagerly awaiting His appearance. By remaining in Kamsas association, they would be able to see the Supreme Personality of Godhead take birth and display His childhood pastimes, and Akrura would later go to Vrndavana to bring Krsna and Balarama to Mathura. The word paryupasate is significant because it indicates that some devotees wanted to stay near Kamsa in order to see all these pastimes of the Lord. The six children killed by Kamsa had formerly been sons of Marici, but because of having been cursed by a brahmana, they were obliged to take birth as grandsons of Hiranyakasipu. Kamsa had taken birth as Kalanemi, and now he was obliged to kill his own sons. This was a mystery. As soon as the sons of Devaki were killed, they would return to their original place. The devotees wanted to see this also. Generally speaking, no one kills his own nephews, but Kamsa was so cruel that he did so without hesitation. Ananta, Sankarsana, belongs to the second catur-vyuha, or quadruple expansion. This is the opinion of experienced commentators.
