One of the many remarkable truths about nature is that death is often a gateway to new forms of life. My favorite illustration of this process is the most powerful incident of death in the known universe: a supernova.

A supernova is how a star dies. Stars are born as hydrogen atoms are drawn to each other in the cold depths of outer space. These atoms huddle together in the dark until their bodies fuse into one. This fusion gives off a burst of energy that can be felt as heat and light. The end product is a new atom called helium. As more and more hydrogen atoms join the group, they start a chain reaction that results in a giant ball of gas that we call a star. Stars burn for billions of years, constantly making new kinds of atoms. You can look out the window on a clear day and see this process happening right before your eyes.

Eventually, these atoms become too big and heavy for this process to continue. When this happens, the inward pressure of gravity overwhelms the outward pressure caused by fusion and the star implodes. Because every action in physics causes an equal and opposite reaction, the star’s implosion results in a dramatic explosion. In that brief moment of tremendous destruction, the light of a single star outshines the entire galaxy.

I imagine that for you, the loved ones of those who have recently died, the pain of grief feels overwhelming in the same way. The felt absence of the one who died seems to outshine every other concern in life. This feeling is very normal and natural. You might wonder: Can my universe ever be the same again? Can any good possibly come from a loss so great? These questions are also very normal and natural.

Here’s how nature answers those questions:

Can the universe ever be the same again? No. A great star has been lost, just as the unique light of your loved one’s presence has faded from this world. We grieve this incalculable loss with you.

Can any good possibly come from a loss so great? Yes! The new atoms forged in the heart of that star get launched into space, where gravity draws them back together over billions of years. They form new bodies like other stars, comets, and planets. On our planet Earth, these atoms came together in just the right way to allow life to form and grow. Today, in the ground beneath your feet, in the air you breathe, and even in the atoms of your own body, you carry the remnants of these deceased stars. Quite literally, you are made of stardust!

The spiritual traditions of the world have observed this process and expressed it in various ways. Some believe in reincarnation while others believe in resurrection. Some believe that our physical life ends while our spirits live on in some mysterious way. What all of these beliefs have in common is the hunch that death is not just an end, but also a gateway to new life, just like a supernova.

I know that your world will never be the same again after the loss of this precious loved one. I invite you, in this time of overwhelming grief, to be patient and caring with yourselves and each other. May the gravitational forces of love draw you closer together and help you pick up the scattered pieces. May the blinding light of loss plant seeds of new life as it fades. And may you remember always the unchanging truth that fires your life with dignity: You are stardust!
