एकोनविंशतिशिवावतारवर्णनम्
Description of the Nineteen Manifestations/Avatāras of Śiva
परिवर्त्ते विंशतिमे भविता व्यास गौतमः । तत्राट्टहासनामाहमट्टहासप्रिया नराः
parivartte viṃśatime bhavitā vyāsa gautamaḥ | tatrāṭṭahāsanāmāhamaṭṭahāsapriyā narāḥ
In the twentieth cycle of change, the Vyāsa will be Gautama. There I shall be known by the name ‘Aṭṭahāsa’, and the people there will be devoted to and delighted by Aṭṭahāsa.
Lord Shiva
Tattva Level: pati
Shiva Form: Bhairava
It teaches that Shiva, the timeless Pati (Lord), compassionately becomes accessible in specific names and forms across cosmic cycles, so beings (paśu) can turn from bondage (pāśa) to devotion and liberation through right orientation to Him.
By declaring a specific divine name and form (Aṭṭahāsa), the verse supports Saguna-upāsanā—worship of Shiva with attributes—commonly centered on the Shiva Linga as the stable, sanctifying focus through which devotees approach the transcendent Nirguna reality.
A practical takeaway is nāma-japa and dhyāna on Shiva in the invoked form—repeating Shiva’s names (including the Panchākṣarī, “Om Namaḥ Śivāya”) with bhakti, supported by Shaiva marks like bhasma (Tripuṇḍra) and rudrākṣa where customary.
