Bhagavad Gita Chapter2.13 God Krishna explains, “Embodied soul continuously passes, in this body, from boyhood to youth to old age, the soul similarly passes into another body at death. A self-realized soul is not bewildered by such a change.”
What we see ourselves is the composition of the body and the spirit. Our body constantly keeps changing – the death of childhood causes adulthood, the death of adulthood causes elderhood, and so on so forth. It’s said there are 8.4 million species on our planet, and every spirit travels through all these yonis, including the time spent in heaven and hell. Spirit beneath us remains the same, only the physical appearance changes.
The one who understands this self-destructing nature of our physical body never suffers the bewilderment.
Birth and death are not our righteousness – it’s of our physical body. Our soul is immortal and keeps changing its physical form as we change the old and outdated clothes. If we keep our attachment to the clothes we wear, we will never be able to replace them.
