Indranīla (Blue Sapphire): Source-Myth, Grades, Tests, Substitutes, and Price
यथा च पद्मरागाणां जातकत्रितयं भवेत् / इन्द्र नीलेष्वपि तथा द्रष्टव्यमविशेषतः
yathā ca padmarāgāṇāṃ jātakatritayaṃ bhavet / indra nīleṣvapi tathā draṣṭavyamaviśeṣataḥ
ดังที่แก้วปัทมรากะ (ทับทิม) มีการจำแนกเป็นสามประเภท ฉันใด แก้วอินทระนีละ (ไพลิน) ก็พึงเข้าใจฉันนั้นโดยไม่ต้องแยกต่างใดๆ
Lord Vishnu (speaking to Garuda/Vinata-putra)
Concept: Systematic classification (jātaka-tritaya) applies consistently across comparable gems; knowledge is transferable by analogy.
Vedantic Theme: Pramāṇa and vyavahāra-jñāna: reliable worldly knowledge arises from consistent criteria and analogical reasoning (upamāna).
Application: When evaluating sapphires, apply the same threefold typology used for rubies; avoid arbitrary distinctions and rely on established categories.
Primary Rasa: shanta
Secondary Rasa: adbhuta
Related Themes: Garuda Purana 1.72.9 (jātaka-tritaya for padmarāga; extended to indranīla)
This verse shows that the text applies systematic, repeatable categories (here, a threefold typology) to evaluate gemstones, indicating a broader concern with lakṣaṇa—recognized characteristics used for consistent judgment.
It does not address the soul’s journey directly; it belongs to an instructional section on classification/characteristics, using rubies and sapphires as examples of uniform criteria.
Use consistent standards when assessing quality—avoid arbitrary exceptions; apply the same evaluative framework across comparable cases.
