1"Bhikkhus, just as, in the last month of the hot season, when a mass of dust and dirt has swirled up, a great rain cloud out of season disperses it and quells it on the spot;

so too, when a bhikkhu develops and cultivates the four jhānas, whenever evil unwholesome states arise, he disperses them and quells them on the spot.

"And how is this so?

Here, bhikkhus, secluded from sensual pleasures, secluded from unwholesome states, a bhikkhu enters and dwells in the first jhāna, which is accompanied by thought and examination,In MLDB I rendered vitakka and vicāra respectively as “applied thought” and “sustained thought.” In this translation they become “thought” and “examination.” The latter is surely closer to the actual meaning of vicāra. When vitakka is translated as “thought,” however, a word of caution is necessary. In common usage, vitakka corresponds so closely to our “thought” that no other rendering seems feasible; for example, in kāmavitakka, sensual thought, or its opposite, nekkhammavitakka, thought of renunciation. When, however, vitakka and vicāra occur as constituents of the first jhāna, they do not exercise the function of discursive thinking characteristic of ordinary consciousness. Here, rather, vitakka is the mental factor with the function of applying the mind to the object, and vicāra the factor with the function of examining the object nondiscursively in order to anchor the mind in the object. with rapture and happiness born of seclusion,
- which is based upon seclusion, dispassion, and cessation, maturing in release;
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal;
- which slants, slopes, and inclines towards Nibbāna.

"It is in this way, bhikkhus, that a bhikkhu develops and cultivates the four jhānas so that whenever evil unwholesome states arise, he disperses them and quells them on the spot."

With the subsiding of thought and examination, he enters and dwells in the second jhāna, which has internal confidence and unification of mind, is without thought and examination, and has rapture and happiness born of concentration,
- which is based upon seclusion, dispassion, and cessation, maturing in release;
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal;
- which slants, slopes, and inclines towards Nibbāna.

With the fading away as well of rapture, he dwells equanimous and, mindful and clearly comprehending, he experiences happiness with the body; he enters and dwells in the third jhāna of which the noble ones declare: ‘He is equanimous, mindful, one who dwells happily.’
- which is based upon seclusion, dispassion, and cessation, maturing in release;
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal;
- which slants, slopes, and inclines towards Nibbāna.

With the abandoning of pleasure and pain, and with the previous passing away of joy and displeasure, he enters and dwells in the fourth jhāna, which is neither painful nor pleasant and includes the purification of mindfulness by equanimity,
- which is based upon seclusion, dispassion, and cessation, maturing in release;
- which has as its final goal the removal of lust, the removal of hatred, the removal of delusion;
- which has the Deathless as its ground, the Deathless as its destination, the Deathless as its final goal;
- which slants, slopes, and inclines towards Nibbāna.
