arishadvargas (six inner enemies - desire, anger, greed, infatuation, pride and jealousy) are responsible for one's misconduct and suffering. If one behaves in the same way as animals, in what way is one superior to them? When one makes proper use of intellect, one will not suffer. All matters relating to the world are like passing clouds. When God is present in everyone and everywhere, how is that one faces hardship and misery? The reason is that one has filled their heart with bestial tendencies. One has to drive them out and cleanse the heart. For instance, in a tumbler filled with water, if you want to fill it with milk, the water has to be poured out. Similarly in order to fill your heart with noble feelings, you have to get rid of the evil qualities.
