'recollection', meditation, contemplation. The six recollections often described in the Suttas (e.g. A.VI.10, 25; D.33) are:
(1) "The noble disciple, Mahānāma, recollects thus: 'This Blessed One is holy, a fully Enlightened One, perfected in wisdom and conduct, faring happily, knower of the worlds, unsurpassed leader of men to be trained, teacher of heavenly beings and men, a Buddha, a Blessed One.'
(2) 'Well proclaimed by the Blessed One is the Doctrine (dhamma), directly visible, with immediate fruit, inviting investigation, leading on to Nibbāna, to be comprehended by the wise, each by himself.'
(3) 'Of good conduct is the Community (Sangha) of the Blessed One's disciples, of upright conduct, living on the right path, performing their duties, to wit: the 4 pairs of men or 8 individuals (s. ariya puggala). This Community of the Blessed One's disciples is worthy of offerings, worthy of hospitality, worthy of gifts, worthy of reverence with raised hands, the unsurpassed field for doing meritorious deeds.'
(4) "The noble disciple further recollects his own morality (sīla) which is unbroken, without any breach, undefiled, untarnished, conducive to liberation, praised by the wise, not dependent (on craving or opinions), leading to concentration.
(5) "The noble disciple further recollects his own liberality (cāga) thus: 'Blessed truly am I, highly blessed am I who, amongst beings defiled with the filth of stinginess, live with heart free from stinginess, liberal, open-handed, rejoicing in giving, ready to give anything asked for, glad to give and share with others.'
(6) "The noble disciple further recollects the heavenly beings (devatā): 'There are the heavenly beings of the retinue of the Four Great Kings, the heavenly beings of the World of the Thirty-Three, the Yāmadevas ... and there are heavenly beings besides (s. deva). Such faith, such morality, such knowledge, such liberality, such insight, possessed of which those heavenly beings, after vanishing from here, are reborn in those worlds, such things are also found in me.' " (A. III,70; VI,10; XI,12).
"At the time when the noble disciple recollects the Perfect One ... at such a time his mind is neither possessed of greed, nor of hate, nor of delusion. Quite upright at such a time is his mind owing to the Perfect One ... With upright mind the noble disciple attains understanding of the sense, understanding of the law, attains joy through the law. In the joyous one rapture arises. With heart enraptured, his whole being becomes stilled. Stilled within his being, he feels happiness; and the mind of the happy one becomes firm. Of this noble disciple it is said that amongst those gone astray, he walks on the right path, among those suffering he abides free from suffering. Thus having reached the stream of the law, he develops the recollection of the Enlightened One...." (A.VI.10).
