atithi–sevā

Ancient Polish proverb: 

"Gość w dom, Bóg w dom"

thought to express the very concept of Polish hospitality - and usually translated as: „A guest in the home is God in the home.”

But, the sense of the proverb is slightly, but meaningfully different: "A guest [entering] into [our] home, is [like] God [entering] into [our] home". 

Idealists, those ancient Poles ---

But OK, nothing to be ashamed of.
