仏ほっとけ神構うな
Meanings
1
don't bother the Buddha, give no heed to God
jocular, humorous
A jocular proverb meaning 'leave well enough alone' or 'don't meddle with things that are fine as they are'. It plays on the similar sounds of 仏 (hotoke) and ほっとけ (leave alone), and 神 (kami) and 構うな (don't bother).
They say 'don't bother the Buddha, give no heed to God,' but you really should leave those two alone.
