SB 8.18.13, Translation and Purport

When the great sages saw the Lord as the brahmacari-dwarf Vamana, they were certainly very pleased. Thus they placed before them Kasyapa Muni, the Prajapati, and performed all the ritualistic ceremonies, such as the birthday ceremony.

According to Vedic civilization, when a child is born in the family of a brāhmaṇa, the birthday ceremony, known as jāta-karma, is first performed, and then other ceremonies are also gradually performed. But when this vāmana-rūpa appeared in the form of a vaṭu, or brahmacārī, His sacred thread ceremony was also performed immediately.
