Mind is said to be of two kinds, the pure and the impure. That which is associated with the thought of desire is the impure, while that which is without desire is the pure.
To human beings, their mind alone is the cause of bondage or emancipation.
That mind which is attracted by objects of sense tends to bondage, while that which is not so attracted tends to emancipation.
When a mind is freed from the desires for objects and controlled, it attains the reality of Atma then it is in the Supreme Seat.
Till the time desires perishes, the mind should be controlled. This is only true wisdom and meditation.
