This quote suggests that selfishness is a self-imposed torture to one’s soul. It implies that when we are selfish, we are so consumed with our own desires and needs that we fail to see the bigger picture. This self-centeredness can lead to a state of constant dissatisfaction and unhappiness because we are never content with what we have, always desiring more for ourselves. This is the "torture" that our soul undergoes.

The quote further suggests that if we could step out of our selfishness, we would be able to see how our actions and attitudes have been causing us pain. We would realize that our selfishness has been blinding us from the truth of our actions and their consequences. By letting go of our selfishness, we free our soul from this self-inflicted torment and open ourselves to a more fulfilling and meaningful existence.

Applying this idea in today’s world or in personal development, it suggests that we should strive to be more selfless in our actions and attitudes. This doesn’t mean we should neglect our own needs, but rather we should consider the needs and feelings of others as well. This can lead to a more balanced and harmonious existence, where we are not solely focused on our own desires but also on the well-being of others.

In a world where individualism is often celebrated, this quote serves as a reminder that true happiness and fulfillment come not from satisfying our own desires but from considering and caring for others. In personal development, it suggests that developing empathy and compassion for others is a crucial step towards self-improvement and spiritual growth.
