Swami Mukundananda
How can I stop feeling discontented about money and possessions?
Be content in worldly things, never in devotion
Looking at those who have more than you brings discontent, so look at people less fortunate than yourself. Be content with your spouse, food and wealth, but never feel you have done enough in devotion.
Be contented in material things. If you keep looking at those ahead of you, discontentment will come, so learn contentment by looking at people less fortunate than yourself.
