Adhyaya 8: Yogasthanas, Ashtanga Yoga, Pranayama-Siddhi, and Shiva-Dhyana leading to Samadhi
सशब्दे सभये वापि चैत्यवल्मीकसंचये अशुभे दुर्जनाक्रान्ते मशकादिसमन्विते
saśabde sabhaye vāpi caityavalmīkasaṃcaye aśubhe durjanākrānte maśakādisamanvite
騒がしい所、あるいは恐れを生む所、祠や蟻塚の近くの堆、凶相の地、悪人に占められた所、蚊などの群がる所——そのような場所では礼拝を行ってはならない。
Suta Goswami
It sets a core puja principle: the worship-space must be sattvic and undisturbed, because external disorder (noise, fear, impurity, hostility) obstructs steady devotion and proper mantra-nyasa in Linga-puja.
Shiva as Pati is ever-pure and accessible, yet the pashu (bound soul) must approach with discipline; avoiding अशुभ (inauspicious) settings reflects the need to reduce pasha-like disturbances that scatter awareness from Shiva-tattva.
Kshetra-shuddhi (selection and purification of the worship site) as a prerequisite for Linga-puja; it parallels Pashupata practice where outer restraint supports inner ekagrata (one-pointedness).
