Ratna-parīkṣā: Vajra (Diamond/Thunderbolt) — Origin, Types, Testing, Defects, Weights, and Royal Auspiciousness
न चापि तण्डुलैरेव वज्राणां धरणक्रमः / अष्टाभिः सर्षपैर्गैरैस्तंण्डुलं परिकल्पयेत्
na cāpi taṇḍulaireva vajrāṇāṃ dharaṇakramaḥ / aṣṭābhiḥ sarṣapairgairaistaṃṇḍulaṃ parikalpayet
The standard of weights (dharaṇa-krama) for the “vajra” is not fixed by rice-grains alone; rather, one should define a single rice-grain (taṇḍula) as equal to eight white mustard seeds (sarṣapa).
Lord Vishnu (in instruction to Garuda/Vinata-putra)
Concept: Pramāṇa (standard measure) must be defined by consistent units, not by vague convention.
Vedantic Theme: Vyavahāra-niyama (order in empirical dealings) supporting satya and fairness.
Application: Use standardized, reproducible measures in trade/valuation; avoid arbitrary or manipulable units.
Primary Rasa: shanta
Related Themes: Garuda Purana 1.68 (ratna-lakshana/ratna-pariksha context)
This verse emphasizes standardizing units used in rites—ensuring offerings and ritual items are measured consistently rather than by vague or variable grain counts.
Indirectly: it supports the correct performance of post-death rites (like śrāddha/piṇḍa), which the Garuda Purana links with aiding the preta’s transition and well-being in the after-death journey.
When performing śrāddha or related observances, follow a consistent traditional standard (or a competent priest’s standardized measure) so the ritual is done carefully and without avoidable error.
