Medhātithi’s commentary (manubhāṣya):
‘Spirituality’— disposition to concentrate one’s attention upon the quest for the true nature of the self;—‘centered’— always thinking of it, he shall remain.

‘Disintrested;’—this re-iterates what has been already said before regarding his not caring for the due fulfilment of Dharma and other things.

‘Nirāmiṣaḥ’—free from longings. Flesh is ‘āmiṣa’, which indicates (figuratively) longing, by reason of the fact that living beings have a great liking for flesh; and this longing is forbidden.

All the rest has already been explained before.—(49).
