where you are going or where you have been are imagination. where you are is the only actual reality. not to say thought and imagination stuff is not a reality, it's just a conceptual reality, mind based, thought based and not present in the now to the 5 senses

zen is to be here now without the attention on the conceptual realities, the thought or mind based ones, to be fully present with what is, not with what one imagines or produces as thought or ideas
