"In Sanskrit, they had sight, taste, touch, smell, hearing -- oh, yes," Nand said as the afternoon waned, carrying on his examination of the ancients' ten senses. Once the whirling particles began to slow, a pale focus was restored to the mind. Sanskrit speakers had the same five we do, he said, called collectively the jnanendriya, the agents of perception. But perhaps the path to sensuality was twice as wide then, as Sanskrit speakers had five senses more -- the karmendriya, the agents of action. These were grasping, walking, excretion, sexual reproduction, and one more so obvious that it's astonishing to think we haven't made it a sixth. For if the senses are the means by which we take in the world, then this one, speech, has to be the ultimate. Consider: In one language, you have five. In another, you have twice as many to speak of. Speech is so powerful, it can double the senses. Now that my own have been altered, I'm beginning to understand how interconnected all the senses are, all five, or ten. Change one, and the others are transformed with it. Change your speech -- the word for "fine," say -- and your sense of vision may be altered, too.
