Agastyopadeśa: Viṣṇupada-stava-sādhanā and Paraśurāma’s Darśana of Hari
यं वेदवादैर्विविधप्रकारैर्निर्णेतुमीशानमुखा न शक्नुयुः / तं त्वामनिर्देश्यमचं पुराममनन्तमीडे भव मे दयापरः
yaṃ vedavādairvividhaprakārairnirṇetumīśānamukhā na śaknuyuḥ / taṃ tvāmanirdeśyamacaṃ purāmamanantamīḍe bhava me dayāparaḥ
He whom even Īśāna and the rest cannot determine through the Veda’s many modes of speech—to You, the indescribable, unborn, primeval, infinite One, I offer praise; be compassionate toward me, O Lord.
