It frames purity (āhāra-niyama) and prāyaścitta as prerequisites for approaching the Linga—disciplining the pashu (individual soul) so it may worship Pati (Shiva) without the disturbances of pāpa and impurity.
By implying that Shiva’s teaching includes detailed dharma and purification, it reflects Shiva as Pati—the regulating and liberating Lord—who provides means to loosen pasha (bondage) through right conduct and atonement.
It highlights śauca-oriented discipline: dietary restraint (bhojya/abhojya) and prāyaścitta as purificatory observances that support Shaiva sādhanā and stabilize the practitioner for puja and inner yoga.
