Do You React to Sensual Inputs?

In Buddhist meditation, Vipassana camps and all, I am told that a lot of disturbances will come. The moment the mind doesn't react to sense inputs, the senses are quiet. It's the mind which gets disturbed when we see something, hear something, smell something and touch and that disturbs the mind. So make an effort not to let those disturbances spread in the mind. You will see, after some time, the sensory inputs don't matter.
