‘The central most important quality of practice is that we do it bravely, without wavering. We cannot do it with a weak heart, full of hesitation; nor can we do it while being concerned with what is to the left or what is to the right, or with what others are doing or thinking, with our physical problems or with how we feel about things, or how insecure we might feel – if we pay attention to each and every thing that comes along, there is no way we can possibly encounter that true essence of mind, cut that root of life and death, or clarify the essence of what it really is to exist. Our training is not a scholarly study. We are not sitting toabsorb philosophical information. If we wanted to do that, we could go to college. We are not doing this for information, but to separate from that dualistically oriented mind. We have to completely throw all of that away or we cannot encounter directly that true root of our life energy.’ (The Path to Bodhidharma)
I should note that this passage comes in a chapter on sesshin; I don’t think it is necessary to be sitting sesshin to cultivate this kind of attitude, but it is definitely a helpful container for doing that. One thing I ponder, as I am sure many other teachers do, is how to stimulate this attitude out in the world.
