Chapter 2 - Verse 13

Body changes Soul remains

Dehinosmin Yatha Dehe Kaumaram Yauvanam Jara
Tatha Dehanthara Prapthihi Dheerastatra Na Muhyati

Even as the body goes through childhood, youth and old age, the soul, on the death of the body, takes another body if needed. The wise men are not deluded by death, says Krishna, assuaging the fears of Arjuna. This is an ancient philosophical truth of the rebirth of the soul upon death. But with the help of modern-day science it's explanation of the changing nature of matter, quantum physics, there is a rational explanation available for such truths.
A baby is born. It grows into a child. The birth of the child is the death of the baby. The birth of the youth is the death of the child. The birth of the old person with grey hair and a bent spine is the death of the smart and good looking youth. After the old person grows and passes away, an event we call death physically, is the birth of a new being in a different form, not seen by our eyes.
Though the physical body changes the essence it contains is unchanging and knows no destruction or transformation. Babyhood is like a cup that contains water. Youth is like a bigger mug that contains more of the same water and old age is like a barrel that contains larger quantity of water. The water is the soul. When the container disintegrates with age, the water still remains in the form of vapour and may fill up some container later on. The wise are not deluded by birth and death says Sri Krishna.
