如是,依正法仪轨恭敬供养上师,尽己所能而不欺诳,然后当从上师处循序领受真言(mantra)与解脱之智。
Suta Goswami (narrating the Shaiva discipline as taught in the Linga Purana tradition)
It establishes that Linga-puja becomes spiritually effective when grounded in sincere Guru-upasana and proper initiation—receiving mantra and right knowledge without deceit and according to dharmic procedure.
Shiva-tattva is approached through a transmitted path: mantra (upaya) and jnana (tattva-bodha). The verse implies Shiva as Pati (Lord) is realized by the Pashu (soul) through ordered instruction that removes Pasha (bondage).
Guru-puja followed by mantra-grahana (initiation/receiving the mantra) and gradual imparting of jnana—an initiatory, stepwise discipline aligned with Pashupata-oriented Shaiva sadhana.
