रुक्मवर्णं द्रुमं पश्येद् गन्धर्वनगराणि च पश्येत् प्रेतपिशाचांश् च नवमासान् स जीवति
rukmavarṇaṃ drumaṃ paśyed gandharvanagarāṇi ca paśyet pretapiśācāṃś ca navamāsān sa jīvati
黄金の色を帯びた樹を見、さらにガンダルヴァ(Gandharva)の都を見、またプレータとピシャーチャ(piśāca)をも見るなら、その者は九か月のみ生きる。
Suta Goswami (narrating to the sages of Naimisharanya)
It frames extraordinary visions as time-bound karmic indicators; in Shaiva practice, refuge in Pati (Shiva) through Linga-upasana is the stabilizing response to such subtle disturbances and omens.
Indirectly: the verse highlights the instability of the subtle world (preta, piśāca, gandharva-visions), implying the need for the unchanging Pati—Shiva-tattva—who transcends such apparitional states and liberates the pashu from pasha.
No single rite is named, but the context supports Shaiva protective discipline—mantra-japa, inner steadiness (yogic dhairya), and Linga-focused worship to remain unattached to fear-inducing visions.
