उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
दारवं तालपर्णं वा आसनं परिकल्पयेत् त्रिसंध्यं तु गुरोः पूजा कर्तव्या हितमिच्छता
dāravaṃ tālaparṇaṃ vā āsanaṃ parikalpayet trisaṃdhyaṃ tu guroḥ pūjā kartavyā hitamicchatā
Man richte sich einen Sitz aus Holz oder aus Palmblättern her; und wer wahres Heil begehrt, hat den Guru zu den drei Sandhyā-Zeiten zu verehren: bei Morgendämmerung, Mittag und Abenddämmerung.
Suta Goswami (narrating Shiva-dharma instructions within the Linga Purana)
It establishes that Linga-oriented Shaiva practice is grounded in Guru-sevā: regular worship of the preceptor at the three sandhyās stabilizes purity, mantra-dīkṣā lineage, and correct pujā-vidhi.
By centering worship on the Guru, it implies Shiva-tattva is approached through Pati’s grace mediated by the teacher—right knowledge and practice remove pāśa for the paśu and lead toward liberation.
Trisandhyā observance with Guru-pūjā—daily discipline aligned to liminal times, supporting Pāśupata-style sādhana (regularity, purity, and initiation-based practice).
