It is endowed with twenty-four syllables and is unsurpassed, being applied in the four sacred times. Next comes the mantra of five hundred (syllables/letters), conjoined with the eight kalās, the divine phases and powers.

The verse classifies Shiva-mantras by their inner structure (syllable-count and kalā-connection), indicating that mantra is not mere sound but a śakti-bearing form of Śiva’s grace that ripens the soul toward liberation.
By describing mantras as endowed with kalās, the text points to Saguna Śiva worship where the Linga is approached through mantra-japa—sound (mantra) and form (Liṅga) functioning together as accessible supports for devotion and realization.
It suggests disciplined mantra-japa performed in the four sacred daily periods (such as dawn, midday, dusk, and night), with attention to the mantra’s prescribed form—supporting Shaiva practice alongside observances like bhasma (tripuṇḍra) and rudrākṣa when taught in context.
