Are you a slave to thought?

Why has thought become so important in all our lives – thought being ideas, being the response to the accumulated memories in the brain cells? Perhaps many of you have not even asked such a question before, or if you have you may have said, ‘It’s of very little importance – what is important is emotion.’ But I don’t see how you can separate the two. If thought doesn’t give continuity to feeling, feeling dies very quickly. So why in our daily lives, in our grinding, boring, frightened lives, has thought taken on such inordinate importance? Ask yourself as I am asking myself – why is one a slave to thought – cunning, clever, thought which can organize, which can start things, which has invented so much, bred so many wars, created so much fear, so much anxiety, which is forever making images and chasing its own tail – thought which has enjoyed the pleasure of yesterday and given that pleasure continuity in the present and also in the future – thought which is always active, chattering, moving, constructing, taking away, adding, supposing?
