yajña-vāstu-gatam - things belonging to the sacrificial arena; sarvam - everything; ucchiṣṭam - remnants; ṛṣayaḥ - the great sages; kvacit - sometimes, in the Dakṣa-yajña; cakruḥ - did so; hi - indeed; bhāgam - share; rudrāya - unto Lord Śiva; saḥ - that; devaḥ - demigod; sarvam - everything; arhati - deserves.

The father of Nābhāga said: Whatever the great sages sacrificed in the arena of the Dakṣa-yajña, they offered to Lord Śiva as his share. Therefore, everything in the sacrificial arena certainly belongs to Lord Śiva.
