Exercising the Mind
All human beings should become accustomed to contemplation, and they need to use their minds in all affairs so that their intellectual force increases day after day. Because humankind is to transcend in all fields and crucial affairs, we should train our minds in all affairs to obtain desirable outcomes. To carry out this task in an orderly fashion, it is beneficial to specify certain times for this task, so that there is no negligence. For instance, the wonders of creation and its immensity, along with contemplation on the unity among the factors of creation, and the relationships and entanglements between creatures and objects, are an excellent food for thought and for contemplation. There should be an understanding that no amount of striving will be pointless since that trains the mind for the path of life while cultivating reliable and robust reasoning for the verities provided to the human.
Therefore, it is incumbent upon every single human being to train their minds to the highest degree, according to their destiny, talent, and intellectual capabilities, and to become wise.
