BY “software translation” i mean a translation that i did myself using Google Translation app : on left column one pastes de texte in Sinhala and translation shows on the right column.
As for Zoysa : yes i read about him.
Assasa : There is the Assasa Sutta which is about contemplating on the right views about i.e. sensual pleasures and (no)self which is a Sutta in itself as Anapanassati Sutta too is.
In other words: perhaps that when translating the latter, one should envisage it separately from Assasa. And so being, translating an-apana as “breathe” “breathing in & out” etc might be right…
