ब्रह्मकृत-ईशानस्तवः तथा विश्वरूपदेवी-प्रकृतिरहस्योपदेशः
शुद्धस्फटिकसंकाशं सर्वाभरणभूषितम् अथ तं मनसा ध्यात्वा युक्तात्मा वै पितामहः
śuddhasphaṭikasaṃkāśaṃ sarvābharaṇabhūṣitam atha taṃ manasā dhyātvā yuktātmā vai pitāmahaḥ
その神聖なる御姿は、汚れなき水晶のごとく輝き、あらゆる荘厳の飾りを具えていた。ついでピターマハ(梵天)は、ヨーガにより内なる自己を結び、心中に観想して御方を禅定した。
Suta Goswami (narrating the Purāṇic account; internal action attributed to Brahmā/Pitāmaha)
It emphasizes mānasa-pūjā (inner worship): before external rites, the devotee—here Brahmā—stabilizes the mind and contemplates the pure, luminous form, aligning the pashu (individual soul) toward Pati (Śiva).
Śiva is indicated as śuddha (untainted) and self-luminous like crystal, suggesting nirdoṣatva (faultlessness) and prakāśa (radiant consciousness) that can be apprehended through dhyāna when the mind becomes yuktātmā (yoga-integrated).
Manasā-dhyāna—focused meditation with a collected, yoked mind (yuktātmā)—a core preparatory discipline aligned with Pāśupata-oriented inner concentration preceding or accompanying Linga-pūjā.
