स्वेच्छाविग्रहसंभव-प्रतिष्ठाफलवर्णनम् (विविधशिवमूर्तिप्रतिष्ठा, लोक-फल, शिवसायुज्य)
त्रिपादं सप्तहस्तं च चतुःशृङ्गं द्विशीर्षकम् कृत्वा यज्ञेशमीशानं विष्णुलोके महीयते
tripādaṃ saptahastaṃ ca catuḥśṛṅgaṃ dviśīrṣakam kṛtvā yajñeśamīśānaṃ viṣṇuloke mahīyate
若塑造(或于三昧中观想)祭祀之主伊沙那(Īśāna)为三足、七手、四角、双首者,则其人在毗湿奴之界受尊崇。依湿婆派之义,此果由观修“主宰”(Pati,湿婆)为一切吠陀仪礼之内在统御者而生:超越其相而又遍入其相。
Suta Goswami (narrating the phala of a prescribed contemplation to the sages of Naimisharanya)
It teaches a specific dhyāna-lakṣaṇa (meditative iconography) of Īśāna as Yajñeśvara, implying that true yajña is fulfilled when its inner Lord (Śiva as Pati) is recognized and worshiped—an idea central to Linga-oriented devotion.
Śiva is presented as Īśāna, the sovereign principle who presides over and perfects Vedic sacrifice—Pati who is beyond form yet can be contemplated through symbolic attributes, granting upliftment even to realms associated with Viṣṇu.
A dhyāna-based upāsanā: mentally forming and contemplating Yajñeśvara-Īśāna with prescribed features, aligning the practitioner (pashu) toward release from pasha through focused devotion and inner yajña.
