正しい座に堅く坐し、真言の義に心を入れて、正しくジャパを行うべきである。座具は絹でも、虎皮でも、布でも、あるいは毛織の敷物でもよい。
Suta Goswami (narrating Shiva-puja and japa-vidhi teachings within the Linga Purana discourse)
It defines the inner and outer discipline for Shiva-oriented sādhana: japa must be done correctly while seated on a proper āsana, with attention fixed on the mantra’s meaning—supporting steady Linga-puja and concentration on Pati (Shiva).
By insisting on absorption in the mantra’s meaning, it points to Shiva as Pati—the supreme consciousness realized through focused mantra-jñāna, where the pashu (individual soul) loosens pāśa (bondage) via disciplined awareness.
Mantra-japa performed in a stable āsana with mantrārtha-anusandhāna (contemplation of meaning), using traditional seat materials (silk, tiger-skin, cloth, wool) to support steadiness and purity in Pashupata-style practice.
