若有人令此帕拉梅湿伐罗真言如是坚固安住于心——则由彼,诸经如同已学;由彼,诸经如同已闻;由彼,一切神圣行持如同已圆满成就。
Suta Goswami (narrating the mantra’s greatness within the Linga Purana discourse)
It teaches that true Linga-worship is internalized: when Śiva’s Parameśvara-mantra abides in the heart, the merit of external rites and scriptural duties is fulfilled through inner devotion and constant remembrance.
Śiva as Pati (the Supreme Lord) is accessible through mantra as living presence in the heart; His grace makes the seeker’s knowledge (study/hearing) and karma (observances) spiritually complete.
Heart-established mantra-sādhana—steady japa with bhāva leading to inner absorption (dhyāna/niṣṭhā), a key Pāśupata-oriented approach where inner realization supersedes mere external performance.
