Death is before me today Like a sick man’s recovery, Like going outdoors after confinement. Death is before me today Like the fragrance of myrrh, Like sitting under sail on breeze day. Death is before me today Like the fragrance of lotus. Like sitting on the shore of drunkenness. Death is before me today Like a well-trodden way, Like a man’s coming home from warfare. Death is before me today Like the clearing of the sky. As when a man discovers what he ignored. Death is before me today Like a man’s longing to see his home When he has spent many years in captivity

That might be the case. Or you could be part of something else. A collective consciousness, of which you are a transient node. Or maybe there is no time at all. What we call time could just be our current state on a progress bar as we process life. Or maybe we're part of a nervous system for some larger construct. Or perhaps we are just reluctantly self-aware iterations of bio computers with fleeting lives that appeared through the chance combination of carbon-based structures.

Who knows. That's the beauty of it, which I personally feel religion and a certain type of confident atheism tend to deny with their respective faith/certainty.

Empty your mind of all thoughts.
Let your heart be at peace.
Watch the turmoil of beings,
but contemplate their return.

Each separate being in the universe
returns to the common source.
Returning to the source is serenity.
