To envy or feel jealous of another’s wealth, achievements, accomplishments, renown, success in love etc. is, to some degree, unavoidable. This in itself is harmless and may even spur us towards higher aims. The danger lurks in the power of these feelings to motivate us to undercut a rival, or engage in other activities which may later cause us outward or inner degradation.
