There are opportunities and advantages which are within the reach of all to strengthen the moral and spiritual powers. The mind can be expanded and ennobled and should be made to dwell upon heavenly things…. Unless it flows in a heavenward direction it becomes an easy prey to the temptation of Satan to engage in worldly projects and enterprises that have no special connection with God. And all zeal and devotion and restless energy and feverish desire are brought into this work, and the devil stands by and laughs to see human effort wrestling so perseveringly for an object that it will never gain, which eludes its grasp…. Schemes and projects which Satan invents ensnare the soul, and poor, deceived human beings go on blindfolded to their own ruin…. TMK 301.3
