उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
ब्रह्मचारिगृहस्थानां यतीनां चैव शोभने सशिरस्कं ततो देहं सर्वमन्त्रेण संस्पृशेत्
brahmacārigṛhasthānāṃ yatīnāṃ caiva śobhane saśiraskaṃ tato dehaṃ sarvamantreṇa saṃspṛśet
اے نیک و مبارک دیوی! برہماچاری، گِرہستھ اور یتی—سب کے لیے—پھر سر سمیت پورے بدن کو ‘سرو منتر’ سے چھو کر پاک کرے، تاکہ شیو پوجا کے لائق ہو جائے۔
Suta Goswami (narrating Shiva-puja procedure within the Linga Purana’s discourse)
It prescribes a preparatory purification: the devotee sanctifies the whole body (including the head) by mantra-touch, making the body a fit instrument for approaching the Linga as Pati (Śiva).
Śiva is implied as the supreme purifier: through mantra connected to Him, the embodied pashu (soul) refines the psycho-physical field, loosening pāśa (bondage) and turning the body-mind toward Śiva-consciousness.
Mantra-sparśa (ritual touching with mantra) as a purification limb of Śiva-pūjā—aligned with Pāśupata discipline where bodily acts are consecrated by mantra before worship.
