In 2013-14, I visited new Vishvnath temple (in BHU), Varanasi. Inside temple, many shlokas are written on its wall. One of them states the suiatable age of marriage, I remember only few words from it:
For man the suitable age of marriage was written as पञ्चविंशति (25) and for woman as षोडश (16).
Can anyone please tell the complete shloka and it's source?
