Let me put your questions in a different order.
“What is bhavadiṭṭhi?”
- I don’t think there is such a term in the Tipitaka.
” Isn’t a Sotāpanna attained by eliminating all diṭṭhis?”
- No. One becomes a Sotapanna by removing the ten types of miccha ditthi and sakkaya ditthi. They may have other minor ditthis.
“If a Sotāpanna eliminates ucchedadiṭṭhi, and thus vibhavataṇhā is removed at the Sotāpanna stage, why isn’t bhavataṇhā eliminated as well?”
- Why do you think the removal of uccheda ditthi leads to the removal of bhava tanha?
- Uccheda ditthi means not believing in the rebirth process. Would not one with uccheda ditthi have kama raga (and thus bhava tanha)?
