देवदारुवनौकसां प्रति ब्रह्मोपदेशः—लिङ्गलक्षण-प्रतिष्ठा-विधिः, शिवमायारूपदर्शनं, स्तुतिः
द्वापरे चैव कालाग्निर् धर्मकेतुः कलौ स्मृतः रुद्रस्य मूर्तयस्त्वेता ये ऽभिध्यायन्ति पण्डिताः

In the Dvāpara age, Rudra is remembered as Kālāgni, and in the Kali age He is known as Dharmaketu. These are the manifested forms of Rudra upon which the learned contemplate—recognizing the one Pati appearing through distinct yuga-forms to govern dharma and burn away pāśa (bondage).
Suta Goswami (narrating to the sages of Naimisharanya)
It frames Linga-centered contemplation as yuga-transcending: devotees meditate on Rudra’s specific yuga-names (Kālāgni, Dharmaketu) while worshiping the one Shiva as Pati, the inner reality behind all forms.
Shiva-tattva is shown as one Lord appearing through distinct functional manifestations across time—burning impurity as Kālāgni and upholding dharma as Dharmaketu—yet remaining the same supreme Pati beyond the yugas.
It highlights dhyāna (contemplation) on Rudra’s forms/names—an inner limb aligned with Pāśupata-oriented practice where remembrance of Shiva dissolves pasha and steadies the pashu (soul) toward liberation.
