“First, the Titpitaka (as it is represents all 3 baskets of Pali texts) didn’t exist when the Buddha was alive. Can I assume that what you meant was that the Buddha prohibited translating his teachings or the Dhamma into Sanskrit.”
That is precisely what #13 of the post “Misinterpretation of Anicca and Anatta by Early European Scholars” says.
- I don’t understand the question. Tipitaka reference is in #13.
- It is in the Vinaya Pitaka. Why does it HAVE TO BE in the Sutta Pitaka?
- There are three Pitakas, including the Abhidhamma Pitaka. All three are relevant.
P.S. I have revised #13 in the post to link to the cited passage in the Vinaya Pitaka.
