MID BRAIN ACTIVATION....

To strengthen yourself you need to have mental clarity or focus. That is possible if there is not so much of excessive thought, so as to generate clouds of unhappiness, suffering, grief, indecision, doubts & negativity - thoughts that your mind produces, thoughts that are weak, useless or wasteful. All of these thoughts cloud your own clarity. Mental focus means to think less, think concretely, concentrate, think in an elevated way & your thought will have an energy of clarity & inner strength that will help you to put it into practice with greater success. You should strengthen yourself to achieve a state of self-control. For this, you need to study yourself, know yourself & understand yourself. You need inner silence, for there not to be so much mental chatter (noise) from thinking, thinking, thinking & thinking. 
On top of that, other people influence you & so you generate even more thoughts. There are so many influences & inner voices that speak to you. With all of that there cannot be clarity. There is the voice of your fears, of your ego, that of desires & greed, there are influences of the past, thoughts emerging from your values, influences of your neighbors, your children, your husband or wife, your mother or father, the influence of your office colleague's opinion, or your best friend, your doctor, your guru, etc. You can listen to many inner & outer voices and, if you are not strong, your mind weakens under so many influences, which has negative effects on your clarity of mind. Because of all of this you have to strengthen your mind, which means, think less; think slower, concentrated & clear thought; with sense & meaning; of quality, based on a healthy & positive motivation. These thoughts are then like arrows, which have positive strength and clarity.
