उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
पुरश्चरणजापी वा अपि वा नित्यजापकः अचिरात्सिद्धिकाङ्क्षी तु तयोरन्यतरो भवेत्
puraścaraṇajāpī vā api vā nityajāpakaḥ acirātsiddhikāṅkṣī tu tayoranyataro bhavet
欲求迅速成就(悉地)者,当成为行持普罗沙遮罗那持诵(puraścaraṇa-japa,具足戒律次第之完整咒修循环)之人,或成为日日恒常持诵者;于此二法之中,当择其一而行。
Suta Goswami (narrating Linga Purana teachings to the sages of Naimisharanya, conveying Shaiva mantra-dharma)
It defines two authorized Shaiva disciplines—puraścaraṇa and nitya-japa—as direct means to quick success in Linga-centered mantra-sadhana, emphasizing steady practice as the core of worship.
By presenting mantra-japa as a reliable path to siddhi, it implies Shiva as Pati—the ever-accessible Lord who responds to disciplined invocation, loosening pasha (bondage) for the pashu (soul) through grace mediated by mantra.
It highlights puraścaraṇa (a complete vow-based mantra cycle) and nitya-japa (daily repetition), both aligned with Pashupata-style inner purification and focused mantra-dharana.
