Дантабхуми сутта,
МН 125 - более подробно о прекращении мышления во второй джхане.
Then the Tathagata trains him further: 'Come, monk, remain focused on the body in & of itself, but do not think any thoughts connected with the body. Remain focused on feelings in & of themselves, but do not think any thoughts connected with feelings. Remain focused on the mind in & of itself, but do not think any thoughts connected with mind. Remain focused on mental qualities in & of themselves, but do not think any thoughts connected with mental qualities.' With the stilling of directed thoughts & evaluations, he enters the second jhana....
Во второй джхане прекращаются и родственные процессы - "замыслы" (санкаппа):
And what are skillful resolves? Being resolved on renunciation, on non-ill will, on harmlessness. These are called skillful resolves. What is the cause of skillful resolves? Their cause, too, has been stated, and they are said to be perception-caused. Which perception? — for perception has many modes & permutations. Any renunciation-perception, non-ill will-perception or harmlessness-perception: That is the cause of skillful resolves. Now where do skillful resolves cease without trace? Their cessation, too, has been stated: There is the case where a monk, with the stilling of directed thoughts & evaluations, enters & remains in the second jhana: rapture & pleasure born of composure, unification of awareness free from directed thought & evaluation — internal assurance. This is where skillful resolves cease without trace.
Самана-мундика сутта, МН 78
http://www.accesstoinsight.org/tipitaka/mn/mn.078.than.htmlРазличение умелых и неумелых замыслов сродно различению умелых и неумелых мыслей в Дведхавитакка сутте:
"Whatever a monk keeps pursuing with his thinking & pondering, that becomes the inclination of his awareness. If a monk keeps pursuing thinking imbued with renunciation, abandoning thinking imbued with sensuality, his mind is bent by that thinking imbued with renunciation. If a monk keeps pursuing thinking imbued with non-ill will, abandoning thinking imbued with ill will, his mind is bent by that thinking imbued with non-ill will. If a monk keeps pursuing thinking imbued with harmlessness, abandoning thinking imbued with harmfulness, his mind is bent by that thinking imbued with harmlessness.
"Just as in the last month of the hot season, when all the crops have been gathered into the village, a cowherd would look after his cows: While resting under the shade of a tree or out in the open, he simply keeps himself mindful of 'those cows.' In the same way, I simply kept myself mindful of 'those mental qualities.'
"Unflagging persistence was aroused in me, and unmuddled mindfulness established. My body was calm & unaroused, my mind concentrated & single. Quite withdrawn from sensuality, withdrawn from unskillful mental qualities, I entered & remained in the first jhana: rapture & pleasure born from withdrawal, accompanied by directed thought & evaluation.

Patisambhidamagga, Treatise on Knowledge, Chapter 34: Attainment of Cessation, 456:
In one who has attained the second jhana the verbal formations (vacisankhara) consisting of vitakka and vicara are quite tranquilized.
