>They word”my” comes from the Sanskrit word “Maya”

Source? I'm seeing that the word "my" comes from proto-Germanic mīnaz (meaning "my") which itself comes from proto-Indo-European méynos (also meaning "my"). PIE predates the Sanskrit language so it doesn't seem there's a shared etymology at all.

Which is pretty much what I expected. The idea that a "myself" could exist is a more intuitive and basic assumption than that "myself" is illusionary; it would make no sense for this equally basic word to stem from such a philosophical perspective. Not that English borrows much directly from Sanskrit anyway. It sounds like someone is trying to push the idea that our 'wiser' ancestors 'knew' the self was illusory through this bad folk etymology. On the contrary I'm pretty sure most of our ancestors would've had a very strong sense of self lol
