Śaṅkarācārya's commentary

Mentally: with discriminative faith. All actions: producing visible and invisible results. As taught in ix.27, do thou dedicate all thy actions to Me. Regarding: regarding Me, Vāsudeva, as the highest goal; his whole self centred in Me. Resorting: resorting to the Buddhi-Yoga (firm faith) as thy sole refuge.
