भौमस्य ब्रह्मणो गुप्त्यै दत्तमग्निमिवारणिः' इति च महाभारते ॥महाक्रमो महाकर्मा
In plain words
"He was given for the guarding of the Veda here on earth, the way the araṇi wood carries the fire laid inside it" — so the Mahābhārata says as well. Then: Mahākrama, whose stride is immense. Mahākarmā, whose works are great.
Close to the Sanskrit
"...given for the protection of the brahman that belongs to the earth, as the araṇi [holds] the fire deposited in it" — thus also in the Mahābhārata. || Mahākrama, Mahākarmā.
