उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
न्यस्ते मन्त्रे ऽथ सुभगे शङ्करप्रतिमो भवेत् जन्मान्तरकृतं पापम् अपि नश्यति तत्क्षणात्
nyaste mantre 'tha subhage śaṅkarapratimo bhavet janmāntarakṛtaṃ pāpam api naśyati tatkṣaṇāt
اے نیک بخت! جب منتر کا نیاس درست طریقے سے ہو جائے تو سادھک شَنکر کی مانند ہو جاتا ہے؛ پچھلے جنموں کے گناہ بھی اسی لمحے مٹ جاتے ہیں۔
Suta Goswami (narrating a Shaiva ritual teaching within the Purva-Bhaga context)
It states that mantra-nyāsa (ritual placement of the Shiva-mantra upon the body and worship) makes the sādhaka fit for Linga-pūjā by instantly burning accumulated pāpa, preparing the pashu (soul) to approach Pati (Shiva).
Shiva-tattva is presented as supremely purifying and transformative: by contact with Shiva-mantra, the limited pashu becomes ‘Śaṅkara-pratima’—a likeness of the Lord—indicating Shiva’s grace that cuts pāśa (bondage) and reveals divine purity.
Mantra-nyāsa—placing the mantra through touch and contemplation (a Pāśupata-leaning preparatory discipline) so the body-mind becomes a fit vessel for Shiva’s presence and for Linga-pūjā.
