Thus, having received from the Guru the supreme mantra and the corresponding liberating knowledge, one should perform daily japa with a clear saṅkalpa, and also undertake the full discipline of puraścaraṇa. In this way the paśu (bound soul) is led toward Pati (Lord Śiva) through mantra-siddhi and right understanding.
Suta Goswami (narrating mantra-sadhana procedure within the Linga Purana’s Shaiva discipline)
It grounds Linga-upasana in authorized initiation: the mantra must be received from a Guru, then stabilized through daily japa and puraścaraṇa, making worship effective and siddhi-oriented rather than merely external.
Shiva is implied as Pati—the supreme goal accessed through mantra and jñāna; the paśu moves from bondage (pāśa) toward Shiva by disciplined practice empowered by right knowledge.
Mantra-japa performed daily with saṅkalpa, supported by puraścaraṇa (a structured regimen of repetition and observances) as a Shaiva sadhana aligned with Pashupata-style discipline.
