पिशाचान्तः स विज्ञेयः स्वर्गस्थानेषु देहिनाम् ब्राह्मे तु केवलं सत्त्वं स्थावरे केवलं तमः
piśācāntaḥ sa vijñeyaḥ svargasthāneṣu dehinām brāhme tu kevalaṃ sattvaṃ sthāvare kevalaṃ tamaḥ
天界の座に至る有身の者たちのうちにも、その幅はピシャーチャ(piśāca)の境にまで及ぶと知るべきである。されどブラフマー界には純粋なるサットヴァのみがあり、不動の界(sthāvara)にはタマスのみがある。
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.
