2.32.2

tatra damyaḥ pañcavidhaḥ skandhagataḥ stambhagato vārigato 'vapātagato yūthagataś ceti //

Those which are tameable fall under five groups: that which suffers a man to sit on its withers (skandhagata), that which allows itself to be tethered to a post (stambhagata), that which can be taken to water (várigata), that which lies in pits (apapátagata), and that which is attached to its herd (yúthagata).
