11.8.21

तावज्जितेन्द्रियो न स्याद् विजितान्येन्द्रिय: पुमान् । न जयेद् रसनं यावज्जितं सर्वं जिते रसे ॥ २१ ॥

tāvaj jitendriyo na syād vijitānyendriyaḥ pumān na jayed rasanaṁ yāvaj jitaṁ sarvaṁ jite rase

tāvat
still
jita-indriyaḥ
one who has conquered the senses
na
not
syāt
can be
vijita-anya-indriyaḥ
one who has conquered all of the other senses
pumān
a human being
na jayet
cannot conquer
rasanam
the tongue
yāvat
as long as
jitam
conquered
sarvam
everything
jite
when conquered
rase
the tongue

Although one may conquer all of the other senses, as long as the tongue is not conquered it cannot be said that one has controlled his senses. However, if one is able to control the tongue, then one is understood to be in full control of all the senses.
