FAQs

What is the importance of this verse in the context of Linga worship?

It grounds Shiva-puja timing in kala (sacred time): understanding waxing/waning tithis helps choose auspicious vrata and abhisheka days, aligning worship with the cosmic order governed through Sun–Moon measures.

How does this verse describe the nature of Shiva (Shiva-tattva)?

By implying that cosmic regulation (kala-niyati) operates through luminaries, it points to Pati (Shiva) as the transcendent Lord of time, while Sun and Moon function as instruments within His ordered manifestation.

What ritualistic or Yogic practice is highlighted here?

Muhurta- and tithi-based observance—planning vrata, japa, and Linga-abhisheka in harmony with paksha progression; for Pashupata-oriented sadhana, this supports disciplined practice through regulated time.
