Shivamurti–Pratishtha Phala: Shivalaya-Nirmana, Kshetra-Mahatmya, Tirtha-Snana, and Mandala-Vidhi
आत्मानं चान्तरात्मानं युगलं बुद्धिमेव च अहङ्कारं च महता सर्वयज्ञफलं लभेत्
ātmānaṃ cāntarātmānaṃ yugalaṃ buddhimeva ca ahaṅkāraṃ ca mahatā sarvayajñaphalaṃ labhet
By the Great Lord, one should realize the self and the Inner Self, together with the pair of principles, the intellect (buddhi), and even egoity (ahaṅkāra); thus one attains the fruit of all sacrifices. (For the paśu, this inner offering becomes the true yajña when oriented to Pati, Śiva.)
Suta Goswami
It shifts yajña from outer fire-ritual to inner offering: mind-principles like buddhi and ahaṅkāra are to be known and surrendered to Pati (Śiva), which is said to yield the fruit of all sacrifices.
Śiva is implied as the antarātmā—present within as the indwelling reality beyond the ego-sense; realizing Him inwardly loosens pāśa (bondage) and turns the pashu toward liberation.
Pāśupata-style inner discipline: discriminating buddhi from ahaṅkāra and orienting the inner self to the antarātmā, treating self-knowledge and surrender as the highest yajña.
