In plain words
He is Ṛddhaḥ because he overflows with supreme virtues like righteousness, wisdom, and dispassion. He is Spaṣṭākṣaraḥ because the clear, elevated syllable Oṃ is his very expression. He is Mantraḥ because he embodies the Ṛg, Yajus, and Sāman Vedas, and is directly revealed through sacred chants. He is Candrāṁśuḥ because, like a cool moonbeam, he soothes hearts tormented by the blazing heat of worldly suffering. And he is Bhāskaradyutiḥ because he shares the dazzling, peerless radiance of the sun.
