One of the missions of the Holy Quran is to train the mind in human beings. What is very important in this regard in the Qur'an is, on the one hand, the use of correct thinking and, on the other hand, the guidance of mankind by this inner force. Thought training is a process that teaches a person how to think and use it to achieve the desired result; Leads. In an overview of the appearance of the Qur'an, God has spoken more than 471 times the derivatives of thinking such as insight, opinion, reminder, reasoning, contemplation and 18 times with the word thinking. The present research is based on inferential research method, which is an argument-based method based on the array of theorems, in the form of first and last theorems. In the process of thinking, the Qur'an uses the existing contexts and, by strengthening this power, guides man from the senses to the senses and provides the ground for his perfect movement. By thinking through the method of proof, man certainly receives a single truth and realizes that the whole system of existence needs causes. In this view, every being, by virtue of the appearance and manifestation of truth, becomes a real and related thing to truth. As by the essence of truth, which is absolute bounty, the grace of existence is manifested, and every creature that has enthusiasm maintains its perfections and moves to study for higher perfections.
