Paṭhamavasasutta 
Paṭhamavasasutta → paṭhamacittavasavattanasuttaṁ (bj) Mastery of the Mind (1st)

“Sattahi, bhikkhave, dhammehi samannāgato bhikkhu cittaṁ vase vatteti, no ca bhikkhu cittassa vasena vattati. 
vase → vasaṁ (mr) “Mendicants, a mendicant with seven qualities masters their mind and is not mastered by it.
Katamehi sattahi?  What seven?
Idha, bhikkhave, bhikkhu samādhikusalo hoti, samādhissa samāpattikusalo hoti, samādhissa ṭhitikusalo hoti, samādhissa vuṭṭhānakusalo hoti, samādhissa kalyāṇakusalo hoti, samādhissa gocarakusalo hoti, samādhissa abhinīhārakusalo hoti.  It’s when a mendicant is skilled at immersion, skilled in entering immersion, skilled in remaining in immersion, skilled in emerging from immersion, skilled in gladdening the mind for immersion, skilled in the meditation subjects for immersion, and skilled in projecting the mind purified by immersion.
Imehi kho, bhikkhave, sattahi dhammehi samannāgato bhikkhu cittaṁ vase vatteti, no ca bhikkhu cittassa vasena vattatī”ti.  A mendicant with these seven qualities masters their mind and is not mastered by it.”

Navamaṁ.
