We are all driven by the desire to satisfy our senses. Most of the time our pain and suffering is simply caused by unrestrained senses. What we see, hear, feel, smell and taste through our senses govern our desires and actions. Understanding our senses and learning to control them helps one to remain balanced and undistracted.
When our senses are not in check and are allowed to get distracted by unwanted desires, it becomes extremely difficult to focus to accomplish a particular task. The single biggest obstacle one faces while accomplishing something is the constant drifting of the mind towards unwanted desires.
In reality there is absolutely no obstacle to accomplish any task. It is almost like actions are governed by the same laws of science. If we begin a certain task and give it enough momentum to keep it going, it will continue to go in the same direction till its completion, unless compelled by an external force!. The external force in this case is another desire.
If only you can learn how to control your other desires and keep your mind focussed on the task at hand, it will always get completed. Trying to do too many things at the same time and trying to juggle between too many things leaves all actions incomplete. Especially when it is so easy to get distracted.
Ask anybody who has tried to accomplish anything really important, they will tell you that the difficult is never the task at hand. The difficulty almost always is learning how to not get distracted by the desire to do too many things. The mind almost never likes to keep doing the same thing. By its very nature the mind wants to pick up different things to do. Only sense control will keep the mind in check.
So what is this sense control? It is the art of observing the senses while they are in action and learning to control their desires. Let us take an example of watching a movie. Movies are made just to captivate your senses. All the effort of movie making is to grab your senses and keep them hooked to the screen. When you start practicing sense control, you will be able to observe how you are being drawn into the movie.
Similarly the desires to eat, to talk to friends, to travel, to socialize, to rest, and to do so many other things distracts one from focussing. If you observe those who have been successful, they almost always have a tunnel vision towards what they want to achieve. They are able to control their senses and desires so well that they can put in a lot more time to focus and achieve what they want to achieve.
It is almost impossible for an impulsive, distracted mind to accomplish anything. The best of behaviors is the one accompanied by sense control and balance. Once you are able to go beyond the strong pull of your senses and desires, it becomes infinitely easy to pick a task and see to its completion. The more control you have over your senses, the more control you have over your life.
