WHAT IS THE CHARACTERISTIC OF HAPPINESS?
Master Jun Hong Lu: What is the characteristic of happiness? It lies in the standard of happiness. What makes a happy person? He is one who is free from greed, hatred and ignorance.
A person with no greed is one with discipline; those who have no hatred are calm; the ones who are free from ignorance have wisdom and they will not do foolish things. A person who does not err, will have happiness.
