[926] *And if one resorts to a secluded seat and bed (rittāsanaṃ sayanaṃ sevato ce):* "Seat" (āsana) is said of that whereon one sits — a bed, a bench, a cushion, a mat, a piece of hide, a spread of grass, a spread of leaves, a spread of straw. "Bed" (sayana) is said of a lodging (senāsana) — a dwelling, a half-gabled house, a mansion, a flat-roofed building, a cave. The bed-and-seat is empty, secluded, well secluded from the sight of unsuitable forms, from the hearing of unsuitable sounds … empty, secluded, well secluded from the five unsuitable strands of sensual pleasure (kāmaguṇa). Resorting to, frequenting, cultivating, and pursuing a secluded seat and bed — hence, "and if one resorts to a secluded seat and bed."
