Empty cannot be more empty

I was trying to shred the recycle bin on my desktop when the message appeared “The recycle bin is already empty and cannot be more emptied”.What a lesson.The enlightenment is also like this.If one is already empty of one’s ego it cannot be further emptied.This realization that there is nothing to be achieved or attained and we are already complete is enlightenment.Already full or already empty is the same situation.Nothing can be added or nothing can be taken out is the sign of being complete.
