One of the names of the Sun-god, as well as a describing epithet attributed to him. A verse in Bhagavadgīta (Bhagavadgita) says raviraṃśumān (ravi is another name of the Sun). Śrīdharasvāmī (Sridharaswami) has mentioned in an annotation that the Sun is aṃśumān (angshuman) among the enlightening rays — jyotiṣaṃ prakāśakānāṃ madhye aṃśumān/ viśvavyāpiraśmiyukto rabiḥ sūryo’ham.
