“And you shall speak of them when you sit at home, and when you walk along the way, and when you lie down and when you rise up.”

行住坐臥
gyou.juu.za.ga

Literally: go / walk – reside – sit – lie down

Alternately: The four fundamental activities: moving about and staying in place, sitting and lying down (to sleep). By extension, everyday life; normal day-to-day activity. All the time, “day in, day out.”

Notes: The 坐 can also be written as 座, with exactly the same pronunciation and meaning.

This compound is apparently derived from a Buddhist chant known as the “Contemplation on the Mind-Ground” sutra (心地観経, shin.ji.kan.gyou). These four activities or states are also referred to as the 四威儀 or 四儀 (both pronounced shigi), the “four postures.”
