In the bottom of an old pond lived some grubs who couldn’t understand why none of their group ever came back after crawling up the lily stems to the top of the water.
They promised each other that the next time, the one who was called to make the upward climb would return and tell what had happened to him. Soon, one of them felt an urgent impulse to seek the surface. He rested himself on the top of a lily pad and went through a glorious transformation, which made him a dragon fly with beautiful wings.
In vain, he tried to keep him promise; flying back and forth over the pond. He peered down at his friends below. Then he realized that even if they could see him, they would not recognize such a radiantly beautiful creature as one of them.
The fact that we cannot see our loved ones and friends, or communicate with them after the transformation we call death, is no proof that they cease to exist.
