The “open mind” is one of the characteristics of Zen Heart. It contains acceptance, forgiveness and patience.
It seems it’s always harder to accept one thing than to refuse, because each person has so many differences from others, and we think that the difference will be the reason to cause unpleasant feeling. In fact, the things we are going to reject will not create any annoyance, but the rejecting attitude will. It doesn’t mean we have no right to refuse. It means we should accept that any kind of existing consists of different causes and conditions. You reject something just because there’s not enough causes and conditions for you to take its’ existence at that moment, not because you “hate” that existence. – no matter if it is a thing, an idea or even an emotion. In this way, we can “forgive” the things we don’t like or don’t agree with, at the same time, we’ll save ourselves from being annoyed “by the “hatred” attitude. We are not able to “accept” or “forgive” because we don’t have enough patience with ourselves and others. The patience can give us more time and opportunities to recognize that there’s no fixed ego behind the forms (things, ideas or emotions…) to be pointed out. In other words, even though an individual must take the responsibility for his mistake, neither “him” nor “mistake” has an ego, and the one who is angry about “him” and “mistake” has no ego either.
Remember to think as you do when we are doing the mediation. We should “accept” everything, such as the sound of air conditioner, the noise of cars outside, the pain or soreness of your body or even the wandering of your mind. They are staying or happening with us, because they are just the manifestation of “causes and conditions”. We just accept their existence, and not cling to them or follow them away from our meditation target. Our mindfulness and concentration on “belly’s rising and falling” are staying with those around us or in us. We are just locked in by the comparative concept, which blocks us to “see” everything as the “One”. The One is not the same as everything, but it is not apart from everything either.
