पिशाचान्तः स विज्ञेयः स्वर्गस्थानेषु देहिनाम् ब्राह्मे तु केवलं सत्त्वं स्थावरे केवलं तमः
piśācāntaḥ sa vijñeyaḥ svargasthāneṣu dehinām brāhme tu kevalaṃ sattvaṃ sthāvare kevalaṃ tamaḥ
स्वर्ग-स्थानों को प्राप्त देहियों में उसकी सीमा पिशाच-पर्यन्त समझनी चाहिए। पर ब्राह्म-लोक में केवल सत्त्व है, और स्थावर-लोक में केवल तम है॥
Suta Goswami (narrating the doctrinal gradation of beings and gunas to the sages at Naimisharanya)
It frames why Shiva-puja and Linga-upasana are prescribed: embodied souls (pashu) move through graded states shaped by the gunas, and worship of Pati (Shiva) is the means to rise beyond tamas/rajas toward sattva and ultimately liberation beyond all gunas.
By contrasting realms dominated by sattva or tamas, it implicitly points to Shiva-tattva as transcendent to the three gunas—Pati who is not bound by the fluctuations that govern the pashu’s embodied destinies.
The takeaway aligns with Pashupata Yoga and Shaiva discipline: reduce tamas (inertia) and stabilize sattva through purity, mantra, and Linga-puja, using devotion and yogic restraint to loosen pasha (bondage) that drives lower rebirths.
