उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
गुणे तु ख्यापिते तस्य सार्वगुण्यफलं भवेत् गुरोर्हितं प्रियं कुर्याद् आदिष्टो वा न वा सदा
guṇe tu khyāpite tasya sārvaguṇyaphalaṃ bhavet gurorhitaṃ priyaṃ kuryād ādiṣṭo vā na vā sadā
Mas quando a sua virtude é proclamada, obtém-se o fruto da excelência completa em todas as qualidades. Deve-se sempre fazer o que é benéfico e querido ao Guru—tenha sido ordenado ou não.
Suta Goswami (narrating the Purana’s teaching to the sages at Naimisharanya)
It frames Linga-bhakti as inseparable from guru-seva: the devotee’s merit matures into “all-round excellence” when the Guru recognizes and guides that virtue, and the practitioner serves the Guru’s welfare and pleasure as a daily discipline.
In Shaiva Siddhanta terms, Shiva as Pati is approached through right conduct under the Guru’s grace; the Guru functions as the living conduit of Shiva’s anugraha (liberating favor) that ripens the Pashu’s virtues and loosens Pasha (bondage).
Guru-seva as a core limb of Pashupata discipline: proactive service—doing what benefits and pleases the Guru even without explicit instruction—supporting steadiness in vrata, puja, and yogic restraint.
