There is an old Japanese saying that keeps cropping up in my conversations with people lately. It is the phrase "sampoh-yoshi."
In this instance, sampoh would be translated as "in three directions." Yoshi can be interpreted as "good," "happy" or "content." Any one of those would apply.
Thus, sampoh-yoshi is a state in which happiness extends in three directions. A kind of "trinity of bliss," in fact.
