Visuddhimagga XII-58

Tattha pādakajjhānacittaṃ nimittārammaṇaṃ.

基础禅（第四禅）心有似相所缘，

Ñ(XII,58): Herein, the basic-jhāna consciousness has the sign as its object;

Parikammacittāni satārammaṇāni vā sahassārammaṇāni vā,

遍作（前三禅）心有百身所缘或千身所缘。

Ñ: but the preliminary-work consciousnesses have the hundred as their object or the thousand as their object.

tāni ca kho vaṇṇavasena, no paṇṇattivasena.

而此等（百千身）是依具体的，不是依概念的。

Ñ: And these latter are objects as appearances, not as concepts.

Adhiṭṭhānacittampi tatheva satārammaṇaṃ vā sahassārammaṇaṃ vā.

决意心亦同样的有百身所缘或千身所缘。

Ñ: The resolving consciousness has likewise the hundred as its object or the thousand as its object.

Taṃ pubbe vuttaṃ appanācittamiva gotrabhuanantaraṃ ekameva uppajjati rūpāvacaracatutthajjhānikaṃ.

彼（决意心）如前面（第四品地遍的解释）所说的安止心，于种姓心之后仅一剎那而生起，是属于色界第四禅。

Ñ: That arises once only, next to change-of-lineage [consciousness], as in the case of absorption consciousness already described (Ch. IV, §78), and it is fine-material-sphere consciousness belonging to the fourth jhāna.
