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
แต่เมื่อสรรเสริญคุณของคุรุ ย่อมได้ผลแห่งความสมบูรณ์พร้อมด้วยคุณทั้งปวง ไม่ว่าจะได้รับบัญชาหรือไม่ก็ตาม จงทำสิ่งที่เป็นประโยชน์และเป็นที่รักแก่คุรุเสมอ.
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.
