Your mind receives uncountable impulses through Senses. Eyes say world looks like you see it. Ears say the world is like you hear it. The nose says the world is as you smell it. Tongue says the world is as you taste it and skin says the world is as you feel it.
These horses pull you in different directions. You get puzzled, broken and helpless. Hardly you move little in one direction then another horse becomes powerful. You feel you remain near and pass by the same crossing.
Mind reflects all impulses it receives outward through reflector senses. This is your behavior. With the result of the puzzled mind your behavior becomes unstable. Your thoughts become different from your feelings and your activities are not in a tune with your thoughts.
Tie these horses in one direction. You need then to wish an aim and the journey begins.
