1SN45:8
.And what, monks, is right concentration? (i) There is the case where a monk — quite withdrawn from sensuality, withdrawn from unskillful (mental) qualities — enters & remains in the first jhana... the second jhana...the third jhana...the fourth jhana...This, monks, is called right concentration."

2.禪那相應第一經SN53:1(菩提尊者英譯相應部P 1762)
Just as the river Ganges slants, slopes, and inclines towards the east, so too one who develops and cultivates the four jhanas slants, slopes, and inclines towards Nibbana.
佛法中的[禪那]並不膚淺,應給予足夠的重視和尊重!
SN53:1說修習多修習[四禪]順于涅槃,道相應SN45中是說[八正道]順于涅槃,這裡則明白說[四禪])
註:Knowledge of ending the taints,as it is actually present,occurs to one who is concentrated,I tell you,and not to one who is not concentrated.So concentration is the path,monk.Non-concentration is no path at all.~~~~~ AN6.64
