Every human being in this world lives with what is known as the pleasure-pain principle. We all want to be happy just as we hate to be unhappy. Then, why do we become unhappy? We become unhappy because of the physical pain of the body, the misery of the mind, and the agony of the ego. It is this triple suffering that is the cause of our unhappiness.
Who doesn't experience pain of the body? Nobody can escape from physical pain, but do we need to suffer? Today there are many medications to take care of all types of physical ailments. But still, we suffer. Why? This is because we are not conscious of the Truth, that we are not the body that suffers.
Then, we experience misery of the wandering mind. It creates Fear – a False Expectation Appearing Real and makes us live with worry, stress, and anxiety. Again, this is because we are not conscious of the Truth that we are not the mind.
The third suffering is that of the ego. The ego becomes agonized as it lives with anger, hate, revenge because we are prisoners of 'I', 'me' and 'mine'. When we realize the Truth and become conscious that we are neither the body, the mind nor the ego, then this triple suffering comes to an end. Unfortunately, because of our ignorance, and by not living in Consciousness, we continue to suffer pain of the body, misery of the mind, and agony of the ego.
