SB 3.24.6

It is clearly stated here that the Lord is always the Supreme Personality of Godhead, although He appeared as the son of Kardama Muni. Fire is already present in wood, but by a certain process, fire is kindled. Similarly, God is all-pervading. He is everywhere, and since He may come out from everything, He appeared in His devotee's semina. Just as an ordinary living entity takes his birth by taking shelter of the semina of a certain living entity, similarly the Supreme Personality of Godhead accepts the shelter of the semina of His devotee and comes out as His son. This manifests His full independence to act in any way, and it does not mean that He is an ordinary living entity forced to take birth in a certain type of womb. Lord Nrsimha appeared from the pillar of Hiranyakasipu's palace, Lord Varaha appeared from the nostril of Brahma, and Lord Kapila appeared from the semina of Kardama, but this does not mean that the nostril of Brahma or the pillar of Hiranyakasipu's palace or the semina of Kardama Muni is the source of the appearance of the Lord. The Lord is always the Lord. Bhagavan madhusūdanaḥ-He is the killer of all kinds of demons, and He always remains the Lord, even if He appears as the son of a particular devotee. The word kardamam is significant, for it indicates that the Lord had some devotional affection or relationship in devotional service with Kardama and Devahūti. But we should not mistakenly understand that He was born just like an ordinary living entity from the semina of Kardama Muni in the womb of Devahūti.
