佛陀曾对诸比库多次宣说:
Iti sīlaṃ, iti samādhi, iti paññā.
Sīlaparibhāvito samādhi mahapphalo hoti mahānisaṃso.
Samādhiparibhāvitā paññā mahapphalā hoti mahānisaṃsā.
Paññāparibhāvitaṃ cittaṃ sammadeva āsavehi vimuccati,
seyyathidaṃ – kāmāsavā bhavāsavā avijjāsavā.
如是戒,如是定,如是慧。
完全修习戒,能获得定之大果报、大功德;
完全修习定,能获得慧之大果报、大功德;
完全修习慧,能使心完全从诸漏中获得解脱,也即是:欲漏、有漏、无明漏。
