It is a fact that the human mind is full of desires but, at the same time, it is also true that man's mind has the capacity for logical thought. When you find that your mind is overwhelmed by desire, examine that desire in the light of reality. Assess it in terms of its potential results, and find out objectively whether it is feasible or not to fulfil it. Then, after examining it completely, if you are satisfied that its results will be beneficial, fulfil your desire.
