Unrighteous desires and efforts for temporal riches and material goods while forsaking spiritual things.

For what is a man profited if he shall gain the whole world and lose his own soul? Matt. 16: 26. They set their hearts upon the vain things of the world, Alma 4: 8 (Alma 31: 27). Lay aside the things of this world, D&C 25: 10. Men's hearts are set so much upon the things of this world, D&C 121: 35.
