A desire for an object arises in the mind. Then one thinks how to get it. Then one exerts to possess it. Desire, thought and action always go together. They are the three threads as it were that are twisted into the cord of karma.
Desire produces karma.
You exert to acquire the object of desire. Karma produces its fruits as pain or pleasure. One has to take births after births to reap the fruits of karma. Have a new angle of vision. Arm yourself with cheerfulness, discernment, alacrity, and undaunted spirit.
