मर्त्यबुद्धिर्न कर्तव्या पुराणज्ञे कदाचन । पुराणज्ञस्सर्ववेत्ता ब्रह्मा विष्णुर्हरो गुरुः
martyabuddhirna kartavyā purāṇajñe kadācana | purāṇajñassarvavettā brahmā viṣṇurharo guruḥ
One should never entertain a merely human view of a knower of the Purāṇas. The Purāṇa-knower is truly all-knowing—Brahmā, Viṣṇu, and Hara (Śiva) in form—and is to be revered as the Guru.
Suta Goswami
Tattva Level: pati
Shiva Form: Sadāśiva
Significance: Deifies the purāṇa-jña as guru embodying Brahmā–Viṣṇu–Hara; in Siddhānta, the guru is revered as Śiva’s representative (śiva-svarūpa) because grace is mediated through him—hence one must not hold ‘martyabuddhi’ toward him.
Role: teaching
Offering: pushpa
It teaches Guru-tattva: the teacher who truly knows the Purāṇas should not be judged as an ordinary person, because sacred knowledge is a manifestation of divine grace (Śiva’s anugraha) leading the soul (paśu) beyond bondage (pāśa).
In Saguna worship, Śiva is approached through visible supports (like the Liṅga) and living embodiments of dharma; the Purāṇa-knower is honored as a living locus of Śiva’s guidance, strengthening devotion, right understanding, and proper ritual orientation.
Śravaṇa (listening to Purāṇa-kathā) with guru-reverence is implied; practically, one may perform guru-pūjā before Shiva worship, apply Tripuṇḍra (bhasma) respectfully, and recite the Pañcākṣarī “Om Namaḥ Śivāya” with the attitude that the Guru grants Śiva-jnāna.
