kasayo madhuras tiktah

 katv amla iti naikadha

bhautikanam vikarena

 rasa eko vibhidyate

 

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

Although originally one, taste becomes manifold as astringent, sweet, bitter, pungent, sour and salty due to contact with other substances.
