"Some Christian saints did the same,especially the hermits"
Christian theologian, Augustine, abandoned his lover and their child although, unlike Augustine, the Buddha left his family in comfort and safety.
Augustines lover left him, and went back to her people (no one knows why) and his son went onto get an education - showing much promise - and died at the age of 16.
He didn't walk off and abandon them.
Absolutely false. His lover left him, for reasons unspecified, but he raised their son in his monastery after she left and they even wrote a book together.
His son died tragically at the age of 16 - historians suspect a pox variant that took the lives of other monks as well.
No need to spread lies about St. Augustine.
