SN 10.1 Indaka Vagga is about a conversation between a yakkha and the Buddha. The yakkha asked the Buddha how does one obtain the body.
I read a dhamma book that mentions this sutta in Pali:
Paṭhamaṃ kalalaṃ hoti, kalalā hoti abbudaṃ.
Abbudājāyate pesi, pesi nibbattatī ghano.
Ghanā pasākhājāyanti, kesā lomā nakhāpi ca.
The author translated the Pali text into English:
First there is the kalala; from the kalala comes the abbuda; From the abbuda the pesī is produced; from the pesī the ghana arises; From the ghana emerge the limbs, the head hair, body-hair, and nails.
Any learned friends here could shed some insight into what these bold Pali words mean? The author of the dhamma book did not elaborate on them but he did compare them with things like embryo, egg, water of washed meat…etc. They appear to be one manifestation of Nibbatti Lakkhana.
