Paññā sutta - Wisdom
"Bhikkhus, there are these eight causes and conditions that lead to the to the attainment, further development, growth, cultivation, and fulfillment of wisdom that pertains to the fundamentals of the spiritual life. What are these eight?
1 Here, bhikkhus, a bhikkhu lives depending on the Teacher, or on a certain fellow practitioner in the role of a teacher, where an acute sense of right and wrong and fear of wrongdoing are established in him, along with affection and respect towards the teacher. This, bhikkhus, is the first cause, the first condition that leads to the attainment, further development, growth, cultivation, and fulfillment of wisdom that pertains to the fundamentals of the spiritual life.
2 He, while living depending on the Teacher or a certain fellow practitioner in the role of a teacher, where an acute sense of right and wrong and moral dread are established in him, along with affection and respect towards the teacher, from time to time approaches them and thoroughly asks and inquires: 'Venerable sir, how is this? What is the meaning of this?' Then those venerable ones reveal what is not yet revealed, make clear what is not yet made clear, and dispel doubts about various teachings that give rise to uncertainty. This, bhikkhus, is the second cause, the second condition that leads to the attainment, further development, growth, cultivation, and fulfillment of wisdom that pertains to the fundamentals of the spiritual life.
3 He, having heard that Dhamma, accomplishes it with two forms of seclusion — physical seclusion and mental seclusion. This, bhikkhus, is the third cause, the third condition that leads to the attainment, further development, growth, cultivation, and fulfillment of wisdom that pertains to the fundamentals of the spiritual life.
4 He is virtuous, dwelling restrained by the moral code of conduct, mindful of proper behavior and keeping to suitable places, seeing danger even in the slightest faults, and having undertaken, he trains in the training guidelines. This, bhikkhus, is the fourth cause, the fourth condition that leads to the attainment, further development, growth, cultivation, and fulfillment of wisdom that pertains to the fundamentals of the spiritual life.
5 He is very learned, who remembers what he has heard, and one who accumulates knowledge. Those teachings which are beneficial in the beginning, beneficial in the middle, and beneficial in the end, of significance, well-phrased, altogether complete, and completely pure — such teachings are well-learned by him, remembered, practiced, mentally recollected, and thoroughly penetrated by view. This, bhikkhus, is the fifth cause, the fifth condition that leads to the attainment, further development, growth, cultivation, and fulfillment of wisdom that pertains to the fundamentals of the spiritual life.
6 He lives with energy aroused for the abandonment of unwholesome qualities and the attainment of wholesome qualities. He is strong, striving diligently, and does not shirk taking responsibility for wholesome qualities. This, bhikkhus, is the sixth cause, the sixth condition that leads to the attainment, further development, growth, cultivation, and fulfillment of wisdom that pertains to the fundamentals of the spiritual life.
7 When associating with the Saṅgha, he does not engage in idle chatter or talk about worldly matters. He either speaks the Dhamma himself or encourages others to do so, and he does not disrespect the noble silence. This, bhikkhus, is the seventh cause, the seventh condition that leads to the attainment, further development, growth, cultivation, and fulfillment of wisdom that pertains to the fundamentals of the spiritual life.
8 He dwells seeing the arising and passing away of the five aggregates that are subject to being held onto as a self: 'Such is form, such is the arising of form, such is the passing away of form; such is sensation, such is the arising of sensation, such is the passing away of sensation; such is perception, such is the arising of perception, such is the passing away of perception; such are volitional formations, such is the arising of volitional formations, such is the passing away of volitional formations; such is consciousness, such is the arising of consciousness, such is the passing away of consciousness.' This, bhikkhus, is the eighth cause, the eighth condition that leads to the attainment, further development, growth, cultivation, and fulfillment of wisdom that pertains to the fundamentals of the spiritual life.
His fellow practitioners hold him in esteem, thinking: 'This venerable one lives depending on the Teacher, or on a certain fellow practitioner in the role of a teacher, where an acute sense of right and wrong and moral dread are established in him, along with affection and respect towards the teacher. Surely, this venerable one knows and sees clearly.' This quality too, bhikkhus, leads to endearment, respect, cultivation, harmony, and unity.
