It highlights tapas and niyama as concentrated inner disciplines that generate spiritual potency—yet in Shaiva understanding, such power becomes auspicious only when directed to Pati (Shiva) through right devotion, often expressed through Linga-upāsanā.
Implicitly, it contrasts created power (tapas-born force) with the Supreme Lord as Pati: beings may strain the body and gain potency, but liberation and true auspiciousness arise from alignment with Shiva-tattva rather than mere self-mortification.
Ugra-tapas supported by strict niyama—an ascetic regimen akin to preliminary yogic discipline; it suggests the power of restraint and heat (tapas) that, when Shaiva-directed, becomes a limb of Pashupata-oriented practice.
