So that your sentient type can learn how to eliminate the distracting thought. While the distracting thought is affecting your sentient type, your sentient type is also trying to fight it. Supported by your concept, your sentient type can only be affected by the distracting thought to a limited level, and as the experience accumulates, your sentient type can slowly learn how to resist the influence from the distracting thought arising from your attitude. Therefore, before you learn how to control your attitude, you must learn how to control your concept. If you try to eliminate the distracting thought in your beginning of learning how to control your attitude, you may end up failure because your groundwork is not good enough or you are unable to completely eliminate the distracting thought, and accordingly you can not learn how to control your attitude. So you must not try to eliminate the distracting thought right from the beginning, but step by step, wait until your sentient type learns how to eliminate the distracting thought, and you will know how to handle the distracting thought every moment it arises.
