المعنى
Advising someone not to push themselves too hard, especially when tired or unwell.
The components of this phrase have roots in classical Japanese and the development of honorific language. '無理' (muri) itself is a compound of '無' (mu - none, not) and '理' (ri - reason, logic), meaning 'unreasonable' or 'impossible'. The honorific 'ご' (go) and the honorific verb 'なさる' (nasaru) have evolved over centuries to express politeness and respect in Japanese communication.
