Śaṅkarācārya's commentary

The embodied one (Kṣetrin), the Supreme Self (Paramātman), is one and illumines all bodies, the whole material being (Kṣetra), from the Avyakta down to the unmoving objects, from the 'Great Elements' down to 'firmness' (xiii.5-6). The illustration by means of the sun serves here a double purpose with reference to the Self — showing that, like the sun, the Self is One only in all bodies, and that like the sun, He is unsoiled.
