Suta Goswami (narrating the Linga Purana teaching to the sages; internal source-text likely describing Shiva-mantra greatness)
It frames Shiva-mantra as the practical core of Linga-pūjā: simple to recite, yet capable of fulfilling all intended spiritual and worldly aims, making mantra-japa central to worship of the Linga as Pati (Lord).
By calling the mantra the “primal” and the “seed of all vidyās,” the verse implies Shiva-tattva as the foundational consciousness (Pati) from which knowledge and power arise, and through which the pashu (soul) can move beyond pāśa (bondage).
Mantra-japa (repetition) as a Pāśupata-aligned sādhanā—easy utterance with focused intent—presented as a direct means to siddhi and inner purification supporting Linga-pūjā.
