viṣayābhilāṣajanakā gītaśabdādayo bhāvā ucyante | tatrāprasaṅgaḥ punaḥ punarasevanam |

For the Kṣatriya he ordained protecting of the people, giving of gifts, sacrificing and studying, as also abstaining prom being addicted to the objects of sense. (89).

Medhātithi’s commentary (manubhāṣya):
What are referred to here are such things as Musical Sounds and the like which tend to give rise (in the minds of men) to a longing for the objects of sensual enjoyment; and the ‘abstaining from being addicted to them’ means not being attached to them; that is, not to have recourse to them frequently. (89).
