Translation of Parayana - definition Is it correct to translate 'parayana' as 'the other shore'? Or is there another and better synonym ?
A recurrent image in [Pali Canon] is of life as a raging flood — a flood of birth, aging, and death; sorrow and lamentation; stress and suffering. The purpose of spiritual practice is to find a way across the flood to the safety of the far shore [parayana].


However:

It seems to me parayana has a connotation of "the ultimate". I guess you could also call it "completion".
