CONTROL OF MIND
One of the commonest habits of the mind is its wandering habit. It cannot stick to one point. It's nature is like that of air. Sri Krishna says in the Gita:
*"*O mighty-armed Arjuna! the mind is hard to curb and restless; but it may be curbed through constant practice and dispassion.*"
The destruction of desires and control of the senses are essential steps towards the control of the mind. It is desire that makes the mind restless.
The senses run after objects and the mind also follows them, just as a dog follows the master. Therefore, if you wish to check this wandering nature of the mind, you have to renounce all kinds of desires and control the senses first. Then alone will you be successful in concentration, will-culture, memory-culture, and thought-culture.
