Ground-testing procedures
bhūmi-parīkṣā
cal-bhumi-parikshaDefinition
The battery of site tests of BS 53.91–94: (1) refill test — a pit one hasta wide and deep, refilled with its own earth: shortfall harmful, level moderate, surplus blessed; (2) water test — fill with water, walk a hundred paces and back: undiminished water is blest; (3) weight test — an adhaka of the dug earth weighing 64 palas is very favorable; (4) lamp test — four wicks facing the quarters in an unbaked pot in the pit: the longest-burning wick's direction names the favored varna; (5) flower test — four varna-colored flowers overnight: the unfaded one names the flourishing varna. The same verses add: any site is auspicious for one whose heart rejoices there.

Other attributes
- Formula
- as enumerated; divisor/remainder structure not applicable
- Heart Criterion Note
- The closing criterion makes the tester's own felt response a valid instrument — Bhat reads it psychologically and cross-refs BS 75.3 [MODERN — M.R. Bhat (1981)]. The single most direct person-site resonance statement in the chapter; prana-chain candidate, tagged honestly: the text says the heart's joy marks auspiciousness, no mechanism given.
- Modern Note
- Bhat connects the lamp test to a Kerala text and his own 1968 symposium paper [MODERN — M.R. Bhat (1968/1981)].
