Lal mentioned: “After “completing” Samma Samadhi, one goes through two more stages to attain the Arahanthood: Samma Nana and Samma Vimutti.”
This is mentioned in The Great Forty discourse in MN 117.
“Therein, bhikkhus, right view comes first. And how does right view come first? In one of right view, right intention comes into being; in one of right intention, right speech comes into being; in one of right speech, right action comes into being; in one of right action, right livelihood comes into being; in one of right livelihood, right effort comes into being; in one of right effort, right mindfulness comes into being; in one of right mindfulness, right concentration comes into being; in one of right concentration, right knowledge comes into being; in one of right knowledge, right deliverance comes into being. Thus, bhikkhus, the path of the disciple in higher training possesses eight factors, the arahant possesses ten factors.
