Śreyas and Paramārtha: The Ribhu–Nidāgha Teaching on Non-Dual Self
Advaita
विज्ञानं परमार्थोऽसौ वेत्ति नोऽतथ्यदर्शनः । वेणुरंघ्रविभेदेन भेदः षङ्जादिसंज्ञितः ॥ ३२ ॥
vijñānaṃ paramārtho'sau vetti no'tathyadarśanaḥ | veṇuraṃghravibhedena bhedaḥ ṣaṅjādisaṃjñitaḥ || 32 ||
ผู้ใดรู้วิชญาณและปรมารถะ ผู้นั้นเป็นผู้เห็นตถตา; ผู้เห็นผิดย่อมไม่รู้. ดุจขลุ่ยที่ความต่างแห่งรูนิ้วทำให้จำแนกเสียงเรียกว่า ษัฑชะ เป็นต้น.
Sanatkumara (teaching Narada in a Moksha-Dharma discourse; using a technical analogy from musical science)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It teaches viveka: the realized knower apprehends paramārtha (ultimate truth), while the deluded remain in atathya-darśana (false seeing). The flute-note analogy shows how apparent differences arise from conditions, not from the essence.
By implying that devotion should be grounded in right vision: when perception is purified, the seeker recognizes the One Reality behind changing names and forms—supporting steady Vishnu-bhakti rather than devotion based on confusion or mere externals.
It gestures toward Śikṣā (phonetics/sound discipline) and nāda-based understanding: like notes (ṣaḍja etc.) arising from precise finger/air positions, spiritual insight also depends on correct method and discernment.
