The humans are considered to have higher or better existences because of the thoughts and behavior we have, just as we can see the difference in thought, conduct, and happiness between us humans and those in the animal realm.
At this time, we have obtained a human body that has a human existence in this world. When we have the pleasant and unpleasant experiences of human beings we express different states of happiness and unhappiness. We are like children who wander through happiness and unhappiness, laughing and smiling one moment and crying the next.
What is the cause of our happiness and unhappiness that change like the clouds in the sky?
