Seven offerings without money

I happened to know the seven offerings without money. This seems to be the Buddhist lesson written in a sutra.

Shasin-se : volunteer service
Wagan-se : warm smile
Shinryo-se : care for others
Jigan-se : peaceful eyes
Aigo-se : gentle words
Bousha-se : giving shelter
Shouza-se : offering a seat

I like the word "Wagan-se". "Wagan" can be called "Nigi-omo" in Japanese. I put a peper written these words on the door wall of my room. I'd like to try these seven offerings every day.
