CC Antya 6.225

vairāgī hañā kare jihvāra lālasa
paramārtha yāya, āra haya rasera vaśa
Word for word: 
vairāgī hañā — being in the renounced order; kare — does; jihvāra — of the tongue; lālasa — lust; parama-artha — the goal of life; yāya — goes; āra — and; haya — becomes; rasera vaśa — dependent on taste.
Translation: 
“If a renunciant is eager for his tongue to taste different foods, his spiritual life will be lost, and he will be subservient to the tastes of his tongue.
