If you are captivated by the past, then you can't make a move. But if you have the faintest, slightest doubt of your existence, the faintest suspicion that it could be
changed -- any progressive mentality, rebellious approach, revolutionary approach, whatever -- that breeds further freedom. In other words, the potential of the
embryonic enlightened mind in us can't be undermined by the heavy karma of the past all the time. Sooner or later it's going to break through. So we are not
entrapped in karma, particularly. There is free choice from that point of view.
