How Vipassana can help break the habit pattern of the mind ~ S.N.Goenka

You have started changing the habit pattern of your mind by observing sensation and understanding its nature of impermanence. This stops the blind habit pattern of reacting to the sensation and multiplying the vicious cycle of misery.

Initially in an hour you get a few seconds or a few minutes of not reacting. But eventually, with practice, you reach a stage where throughout the hour you do not react at all. At the deepest level you do not react at all. A deep change is coming in the old habit pattern.
