When Buddha says “All is illusion,” he isn’t saying that nothing is real. He’s saying that your mind’s projections onto reality are illusions. He’s saying that the elements in the universe that form every physical thing we see—solid, liquid, gas—if they’re taken down to a subatomic level, they don’t exist. Therefore all we see is an illusion, because it’s shape or form, not true essence.
what we see and experience may very well be illusionary, but just because we can’t measure/detect it doesn’t mean there’s no real fundamental/elemental substance at the base of all of it.
