A lazy person lives in suffering, mixed up with bad, unskillful qualities, neglecting their heart’s great goal. But an energetic person lives happily, secluded from bad, unskillful qualities, fulfilling their heart’s great goal. The best isn’t reached by the worst. The best is reached by the best. This spiritual life is the cream, mendicants, and the Teacher is before you. So you should rouse up energy for attaining the unattained, achieving the unachieved, and realizing the unrealized, thinking: ‘In this way our going forth will not be barren, but will be fruitful and fertile. And the services of those whose robes, almsfood, lodgings, and medicines and supplies for the sick we enjoy shall be very fruitful and beneficial for them.’ That’s how you should train. Considering what is good for yourself, mendicants, is quite enough for you to persist with diligence. Considering what is good for others is quite enough for you to persist with diligence. Considering what is good for both is quite enough for you to persist with diligence.”

At Sāvatthī. “Mendicants, I say that the ending of defilements is for one who knows and sees, not for one who does not know or see. For one who knows and sees what? ‘Such is form, such is the origin of form, such is the disappearance of form. Such is feeling … Such is perception … Such are choices … Such is consciousness, such is the origin of consciousness, such is the disappearance of consciousness.’ The ending of the defilements is for one who knows and sees this.
