Where did it go?
Now you are 20, 40 or 50 years old, but this time and space, from the moment you were born till just now, where did it go? There is no way in the world you can show me where this time and space from the time you were born to just this moment is. All that remains is some vague memory even of yesterday. Even 30 seconds ago you cannot remember. So, if you understand that world, you attain moment world. That means moment to moment, clear, clear, clear. What are you doing just now? If you attain that then you can perceive your situation.
