It is said by the ancients that the six vices are desire, anger, miserliness, confusion, pride and jealousy. It is these vices that keep us trapped in samsara.
Desire keeps us chasing after things that do not bring us lasting peace or happiness. Not all desires of course are bad. We desire food, water, shelter, and other things that are needed. Desiring sensual items however leads us down the road to suffering.
Anger is a fire that burns us and people around us. Anger is like drinking salt water as it only makes one more thirsty. The way to defeat anger is through compassion.
Miserliness is does not make one rich, but poor in helping others or even ourselves. It is fine to be thrifty and live simply, but being a miser creates unhappiness in the heart. Generosity is one of the three treasures spoken of in the Tao Te Ching, verse 68.
Confusion is brought on by delusions, not seeing the truth as it is, but as we want it to be. We want things our way and are befuddled and frustrated when we do not get our way. My friends, there are billions of people on this planet. How could it be possible that we all get our way?
Pride does not allow us the gift of humility. It is by being lower, that one is higher. It is pride that often stands in the way of reasoning and the settlement of differences.
Jealousy keeps us away from contentment and peace. We must learn to cultivate sympathetic joy for others. When we have joy in the heart, there is no room for jealousy.
The ancients have said that if one can rid themselves of all these vices, one can be said to be pure of mind.
