The Exposition of the Nityā-paṭala
व्योम्ना प्रकाशमानत्वं ग्रसमानत्वमग्निना । तयोर्विमर्श ईकारो बिंदुना तन्निफालनम् ॥ ४ ॥
vyomnā prakāśamānatvaṃ grasamānatvamagninā | tayorvimarśa īkāro biṃdunā tanniphālanam || 4 ||
By space (vyoman) there is the condition of shining forth; by fire (agni) there is the condition of consuming. The reflective contact (vimarśa) of these two becomes the vowel “ī”; and by the bindu (nasal point) that sound is brought to completion (niphālana).

Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It frames mantra-sounds as arising from cosmic principles (ākāśa/space and agni/fire), implying that correct phonetic formation is not merely linguistic but a sacred alignment with tattvas.
By emphasizing precise sound-completion (through ī-kāra and bindu), it supports bhakti through disciplined japa and mantra-recitation—devotion expressed as correctly articulated sacred sound.
Śikṣā (Vedic phonetics): how vowels and nasalization/bindu are treated as technical features in mantra pronunciation and completion of utterance.
