Samādhiparikkhārasutta  Prerequisites for Immersion

“Sattime, bhikkhave, samādhiparikkhārā.  “Mendicants, there are these seven prerequisites for immersion.
Katame satta?  What seven?
Sammādiṭṭhi, sammāsaṅkappo, sammāvācā, sammākammanto, sammāājīvo, sammāvāyāmo, sammāsati.  Right view, right thought, right speech, right action, right livelihood, right effort, and right mindfulness.
Yā kho, bhikkhave, imehi sattahaṅgehi cittassekaggatā parikkhatā, ayaṁ vuccati, bhikkhave, ariyo sammāsamādhi saupaniso itipi saparikkhāro itipī”ti. 
sammāsamādhi → samādhi (sya-all) Unification of mind with these seven factors as prerequisites is what is called noble right immersion ‘with its vital conditions’ and also ‘with its prerequisites’.”
