The mind is a bundle of thoughts, a complex collection of wants and wishes. As soon as a thought, desire or wish raises its head in the mind, the intellect must probe its value and validity. Is it good or bad? Will it help or hinder? Where will this lead? Where will it end? If the mind does not submit to this probe, it will land itself on the path of ruin. If it does and obeys the intelligence, it will move along the right path.
