According to Wikipedia, the bhagavad gita was written around 200 BC, whereas stoicism originated in 400 BC. Admittedly, this was just the result of some very cursory research, the Buddhist philosophy could go back further than the writing itself, but it seems to me like they independently arise around the same time (that being around 200 years difference, lol) but you really need to be careful saying stuff like that. I’ve made the same mistake dozens of times where I confidently state something, only for it to be disproven by a minute of googling.

The Bhagavad Gita is a synthesis work of even older teachings going back a thousand years before it was written in that book.
