Just as a candle cannot burn without fire, men cannot live without a spiritual life. Buddha
Buddha tries to make a point here.
A candle cannot burn without fire. It needs the fire to melt, to exist as a candle. Similar to the fire needing oxygen.
Men cannot live without a spiritual life. We need something to believe in. We need to look inside ourselves and understand our mind. We need something spiritual to fully comprehend life.
If you didn’t understand that, keep practicing. You will soon see the benefits of a spiritual practice.
Best of luck,
