Possibility

The mind is never different from the thoughts it thinks. Thus no thought, no mind.

weakness

The only weakness of human mind is that it cannot concentrate on present events. It always wander in past and future. Making a new habit requires continuous efforts over a long period of time. Over time the habit becomes the nature of the person. The habit to remain in present creates a void in mind which in turn amass a huge energy which can be used for doing positive things.
The life force is at its maximum when the mind is dead(in present mind actually dies). The force goes on increasing thus making the person, A legend.
