The Birth of Lord Krṣṇa
209
was the sound of mild waves, and above the sea there were clouds in the sky which began to thunder very pleasingly.
When things were adjusted like this, Lord Viṣṇu, who is residing within the heart of every living entity, appeared in the darkness of night as the Supreme Personality of Godhead before Devakī, who appeared as one of the demigoddesses. The appearance of Lord Viṣṇu at that time could be compared to the rising of the full moon in the sky on the eastern horizon. The objection may be raised that since Lord Krṣṇa appeared on the eighth day of the waning moon, there could be no rising of the full moon. In answer to this it may be said that Lord Krṣṇa appeared in the dynasty which is in the hierarchy of the moon; therefore, although the moon was incomplete on that night, because of the Lord's appearance in the dynasty wherein the moon is himself the original person, the moon was in an overjoyous condition, so by the grace of Krṣṇa he could appear as a full moon. To welcome the Supreme Personality of Godhead, the waning moon became a full moon in jubilation.
Instead of  deva-rūpiṇyām , some texts of  Śrīmad-Bhāgavatam  clearly say  viṣṇu-rūpiṇyām . In either case, the meaning is that Devakī has the same spiritual form as the Lord. The Lord is  sac-cid-ānanda-vigraha , and Devakī is also  sac-cid-ānanda-vigraha . Therefore no one can find any fault in the way the Supreme Personality of Godhead,  sac-cid-ānanda-vigraha , appeared from the womb of Devakī.
Those who are not in full knowledge that the appearance and disappearance of the Lord are transcendental ( janma karma ca me divyam ) are sometimes surprised that the Supreme Personality of Godhead can take birth like an ordinary child. Actually, however, the Lord's birth is never ordinary. The Supreme Personality of Godhead is already situated within the core of everyone's heart as  antaryāmī , the Supersoul. Thus because He was present in full potency in Devakī's heart, He was also able to appear outside her body.
One of the twelve great personalities is Bhiṣmadeva ( svayambhūr nāradaḥ śambhuḥ kumāraḥ kapilo manuḥ prahlādo janako bhiṣmaḥ ). In  Śrīmad-Bhāgavatam  (1.9.42), Bhiṣma, a great authority to be followed by devotees, says that the Supreme Personality of Godhead is situated in the core of everyone's heart, just as the sun may be on everyone's head. Yet although the sun may be on the heads of millions and millions of people, this does not mean that the sun is variously situated.
