untouchable

Brisk, yet steady, his capacity for active application to the task he had in hand seemed to flow like constant water from a natural spring. Each muscle of his body, hard as a rock when it came into play, seemed to shine forth like glass.

Anand, Mulk Raj. Untouchable. 15-16. London, England: Penguin, 1986. Print.

In this short passage the imagery of the flow of water gives a sense of smoothness and ease just as the image of glass does. The descriptions give him a sense of fluidity and strength.
