Visuddhimagga V-38

Sabbāneva uddhaṃ adho tiriyaṃ advayaṃ appamāṇanti imaṃ pabhedaṃ labhanti.

一切遍都有上、下、横、无二、无量各种。

Ñ(V,38): The classification 'above, below, around, exclusive, measureless' applies to all kasiṇas;

Vuttañhetaṃ ‘‘pathavīkasiṇameko sañjānāti. Uddhamadhotiriyaṃ advayamappamāṇa’’ntiādi.

即如此说：「有人于地遍作上、下、横、无二、无量想」等。

Ñ: for this is said: 'He perceives the earth kasiṇa above, below, around, exclusive, measureless' (M.ii,14), and so on.
