We spend much of our time thinking about the past or the future, while missing a great deal of what is happening in the moment. When it grows out of proportion, this kind of thinking tends to overshadow the rest of life, so no wonder that life can feel fundamentally incomplete. Thinking also becomes a predominant factor in human interaction, in all relationship, which is probably a dangerous imbalance.
If we say that this imbalance is wrong, then it becomes another problem to solve, which brings more thinking. We might as well forget about the whole thing, rather than constantly checking to see whether life is becoming more balanced.
Perhaps this imbalance or the excessive focus on thinking has something to do with a deeper imbalance in our experience of ourselves. We rarely pay any attention to the sense of being conscious, awake, to the raw sense of “I am” – before trying to define what I am. The intimate sense of “I am” becomes reduced to thinking about ourselves in terms of memories, ideas, pleasant or unpleasant feelings. No wonder that this thinking has so much power. It’s like a rope taking on the appearance of a snake, because the underlying rope (“I am”) is not seen clearly in the shadow, which is thinking. Thinking works through distinctions, so the distinction between “me” and “not me” also becomes a hugely significant thing, which may be called “the sense of separation”.
