In practice, some come to see easily, some with difficulty. But whatever the case, never mind. Difficult or easy, the Buddha said not to be heedless. Just that--don't be heedless. Why? Because life is not certain. Wherever we start to think that things are certain, uncertainty is lurking right there. Heedlessness is just holding things as certain. It is grasping at certainty where there is no certainty and looking for truth in things that are not true. Be careful! They are likely to bite you sometime in the future!
Ajahn ChahThe ultimate truth is like the flavour of an apple which you can't see with the eye or hear with the ear. The only way to experience it is to put the teachings into practice. Once you taste it, you are no longer in any doubt about its flavour and you do not have to ask anyone else. The problem is solved.
Ajahn ChahWhen we sit in meditation and hear a sound, we think, 'Oh, that sound's bothering me.' If we see it like this, we suffer. But if we investigate a little deeper, we see that the sound is simply sound. If we understand like this, then there's nothing more to it. We leave it be. The sound is just sound, why should you go and grab it? You see that actually it was you who went out and disturbed the sound.
Ajahn ChahWhenever we feel that we are definitely right, so much so that we refuse to open up to anything or anybody else, right there we are wrong. It becomes wrong view. When suffering arises, where does it arise from? The cause is wrong view, the fruit of that being suffering. If it was right view it wouldn't cause suffering.
