1. This is not an ancient poem.
Because each sentence has a different origin, it is obviously a famous saying in the form of philosophical thoughts, and the rhyme and other things do not meet the requirements of ancient poetry. It can be regarded as a "wisdom quotation", like those in "Cai Gen Tan".
It is a "Buddhist gatha", I don't know who specifically said it.
