Hello Pali friends,
The verb 'anupassati' refers to maintaining special modes of viewing, e.g.:
aniccato anupassati, no niccato
he views as impermanent, not as permanent
yo attano attānaṃ nānupassati
he who does not view the self by means of the self
and he views its vanishing
In Satipatthana sutta, Sata sutta, and many other similar suttas, Buddha describes four special modes of viewing:
Sato bhikkhave, bhikkhu vihareyya sampajāno, ayaṃ vo amhākaṃ anusāsanī. Kathañca bhikkhave, bhikkhu sato hoti: idha bhikkhave, bhikkhu kāye kāyānupassī viharati ātāpī sampajāno satimā vineyya loke abhijjhādomanassaṃ. Vedanāsu vedanānupassī viharati ātāpī sampajāno satimā vineyya loke abhijjhādomanassaṃ. Citte cittānupassī viharati ātāpī sampajāno satimā vineyya loke abhijjhādomanassaṃ. Dhammesu dhammānupassī viharati ātāpī sampajāno satimā vineyya loke abhijjhādomanassaṃ. Evaṃ kho bhikkhave, bhikkhu sato hoti.
"And how is a monk mindful? There is the case where a monk remains focused on the body in & of itself — ardent, alert, & mindful — subduing greed & distress with reference to the world. He remains focused on feelings... mind... mental qualities in & of themselves — ardent, alert, & mindful — subduing greed & distress with reference to the world. This is how a monk is mindful.http://www.accesstoinsight.org/tipitaka ... .than.html
In these four special forms of viewing, one remains focused on a particular sphere (satipatthana) in & of itself, disregarding other spheres.
= "Contemplating the body." Possessed of the character of body-contemplation, or of observing the body.
Why is the word "body" used twice in the phrase: "Contemplating the body in the body?" For determining the object and isolating it, and for the sifting out thoroughly [vinibbhoga] of the apparently compact [ghana] nature of things like continuity [santati].
Because there is no contemplating of feeling, consciousness nor mental objects in the body, but just the contemplating of the body only, determination through isolation is set forth by the pointing out of the way of contemplating the body only in the property called the body."http://www.accesstoinsight.org/lib/auth ... l#synopsis
Similarly, one can be mindful to maintain some other skilful form of viewing:
Idha bhikkhave, ekacco puggalo sabbasaṅkhāresu aniccānupassī viharati aniccasaññī aniccapaṭisaṃvedī satataṃ samitaṃ abbokiṇṇaṃ cetasā adhimuccamāno paññāya pariyogāhamāno. So āsavānaṃ khayā anāsavaṃ cetovimuttiṃ paññāvimuttiṃ diṭṭheva dhamme sayaṃ abhiññā sacchikatvā upasampajja viharati.
Here, bhikkhus, some person dwells contemplating impermanence in the eye, perceiving impermanence, experiencing impermanence, constantly, continuously, and uninterrpuptedly focusing on it with the mind, fathoming it with wisdom. With the destruction of taints, he has realized for himself with direct knowledge, in this very life, the taintless liberation of mind, liberation by wisdom, and having entered upon it, dwells in it.
