Acharya Prashant explains that there is no such thing as deviation or distraction. The mind simply goes where it has been trained to go. When you feel you are getting distracted, you are not actually being distracted; you are just following the path your mind has been conditioned to take. You go where you have trained your mind to go. To illustrate this, he uses the analogy of a dog. If a dog is walking with you and sees a piece of meat, it will run towards it. You cannot say the dog is distracted; it is simply following its training and nature. Its entire education is to eat meat. Similarly, your mind goes where you have trained it to go day and night. You do what your mind is trained to do. When you set a goal, for instance, to get good marks to get a degree, to get a job, to earn money, and ultimately to have fun, you are essentially opening your books to eventually have fun. So, when a friend comes and offers immediate fun, your mind chooses the shorter route because its ultimate training is to seek pleasure. The mind is doing exactly what it is supposed to do based on its conditioning. It is impossible to have a mind trained for pleasure and simultaneously expect to have concentration on other things. Your ability to concentrate depends on what you are. The problem is not a lack of concentration; you do concentrate deeply, but on whatever you have trained your mind to value. For example, if there is a collage of many pictures, and one is of an attractive person, your eyes will immediately focus on that picture. This is concentration based on your mind's training. To change the object of your concentration, you must change your life itself. You cannot keep your life the same and expect to concentrate on something like studies. You must observe your daily activities: your friends, how you spend your time, the books you read, the shows you watch, and the thoughts you entertain. When these aspects of your life change, your mind will change, and your concentration will change automatically. Just as a kite is trained to spot a mouse from high up and not grass, you must see what you have trained your mind to be. The construction of your mind is done by you through your daily activities.
