Mind is like a large Garud (a bird that according to Hindu mythology is the transport of Lord Vishnu) that has very sharp flight, is very powerful, shrewd, clever, well aware of happenings in all four directions and is brisk like electricity.
Like a maund, the mind is also powerful with eight arms (eight arms of maund-each of 5 seers) 40 hands (each hand is one seer of a maund). Thus it has 160 feet (each feet of a maund is of one pao). Its gait is very sharp and not likely to stop anywhere.
This mind awake or asleep, day or night keeps wandering in all ten directions all the time. It visits all the three worlds in no time.
A bird in a cage cannot fly, but mind though in cage of the body flies to places where no one can reach. It has reach to the cities, mountains, jungles, in the water and even the deserts. (230)
