వాచ్య-వాచక భావములో స్వభావతః సాక్షాత్ స్థితుడైన—ప్రమేయుడగుటచేత శివుడు వాచ్యుడు; మంత్రం ఆయనను సూచించు వాచకమని స్మరించబడును.
Suta Goswami (narrating Shaiva doctrine to the sages at Naimisharanya)
It frames Linga/Mantra worship as a precise mantra–meaning discipline: the mantra is the vācaka (indicator) that leads the devotee’s awareness to Shiva, the vācya (indicated reality), making worship an act of direct Shiva-realization rather than mere symbolism.
Shiva is ‘sākṣāt svabhāvataḥ’—directly present by His own nature—and is the prameya, the realizable object of true knowledge; He is Pati, knowable through right means (mantra) while remaining the intrinsic ground of that knowing.
Mantra-japa with correct artha-bhāvanā (contemplation of meaning): the practitioner holds the mantra as vācaka and meditatively fixes the mind on Shiva as vācya—aligning with Pashupata-oriented inner worship (dhyāna + japa).
