Our mind goes on talking to ourselves.This means that we goes on weaving dreams and travel to imaginary worlds.Emotions images streaming thoughts make up the mind.When these modalities cease mind cease to exist.An enlightens soul can think when he wants to think.As we progress in meditation the number of thoughts progressively reduces.When it becomes standstill the soul manifests.Its benefit is that we are away from disturbing and haunting thoughts.These whirling thoughts wraps the jiva and make it travel to different worlds in the future time to come.
