काष्ठपञ्चविंशतिपलं तण्डुलप्रस्थसाधनम् ॥ कZ_०२.१९.२६ ॥
kāṣṭhapañcaviṃśatipalaṃ taṇḍulaprasthasādhanam
A wooden standard of twenty-five palas shall serve as the implement for establishing/verifying the prastha measure for rice (taṇḍula).
It enables practical field verification: a known weight of rice should correspond to a standard volume, helping detect short-measuring in procurement and retail.
