The Account of Mohinī
Mohinī-upākhyāna
गतिं धर्मस्यातिसूक्ष्मां लोककल्याणकारिणीम् । अनया निकषाश्यांग्या परीक्ष्य स्वर्णभूषणः ॥ ३९ ॥
gatiṃ dharmasyātisūkṣmāṃ lokakalyāṇakāriṇīm | anayā nikaṣāśyāṃgyā parīkṣya svarṇabhūṣaṇaḥ || 39 ||
The course of dharma is exceedingly subtle, yet it brings welfare to the world. As a gold ornament is tested by a touchstone, so should it be examined by this standard of discernment.
Suta (narrating; teaching framed in Narada Purana’s dharma discourse)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It teaches that dharma is subtle and must be verified through careful discernment, with the benchmark being whether it truly promotes the welfare of beings (lokakalyāṇa).
By implying that genuine dharma (including devotional practice) should be tested for purity and real benefit—humility, compassion, and upliftment—rather than mere outward display.
Not a specific Vedāṅga technique, but a nyāya-style principle of examination (parīkṣā): like assaying gold, one should critically evaluate actions and teachings for authenticity and beneficial outcomes.
