The mind is the basis for all the sense organs. Without mental consciousness, the sense organs will not be able to function at all.  From time to time, the senses are likely to go astray.  If a brass vessel is struck with a stick, it will send out vibrations.  Likewise, when someone criticizes you, your mind waves will get excited by the sound waves reaching a certain nerve centre in the brain.  Immediately, an angry reaction occurs.  The stage is set for a quarrel.  Then, there is no control over the mind.  On the other hand, someone else may come and praise you.  You forget yourself and get immersed in joy.  The sense of discrimination may be lost through excessive elation or through deep distress.  When the discriminating power is weak, the mind is prone to pursue wrong courses. To achieve a state of bliss, you must start with the control of senses.  The senses must be directed along the right lines.
