ध्यानयज्ञः, संसार-विष-निरूपणम्, पाशुपतयोगः, परा-अपरा विद्या, चतुर्वस्था-विचारः (अध्यायः ८६)
सर्वमात्मनि संपश्येत् सच्चासच्च समाहितः सर्वं ह्यात्मनि संपश्यन् न बाह्ये कुरुते मनः
sarvamātmani saṃpaśyet saccāsacca samāhitaḥ sarvaṃ hyātmani saṃpaśyan na bāhye kurute manaḥ
当摄心入观时,应于自性之中观见一切——显现者(sat)与未显者(asat)皆然。因为真正于自性中见一切者,其心不复外驰于境。
Suta Goswami (narrating the Linga Purana teaching stream to the sages at Naimisharanya, conveying an Upanishadic-Shiva oriented instruction)
It teaches that true Linga-upāsanā culminates in inner vision: the devotee recognizes all experience as resting in the Self, so worship shifts from merely external ritual to inward absorption (antarmukha bhāva).
By urging one to see both sat (manifest) and asat (unmanifest) in the Self, it points to Shiva-tattva as the all-containing Pati—transcendent yet immanent—within whom the worlds and their potentials are grounded.
It highlights inward-turning meditation and mental restraint: steadiness (samāhita) and withdrawal from external objects, a core movement of Pashupata-oriented yoga that loosens pasha (bondage) for the pashu (soul).
