‘The goal of practice is always to keep our beginner’s mind.
…In the beginner’s mind there is no thought “I have attained something.” All self-centered thoughts limit our vast mind. When we have no thought of achievement, no thought of self, we are true beginners. Then we can really learn something. The beginner’s mind is the mind of compassion. When our mind is compassionate, it is boundless.’
Shunryu Suzuki, Zen Mind, Beginner’s Mind, via On The Way: The Daily Zen Journal 12 February 2015
If you’ve been frustrated that you haven’t been attaining the perfection that practice supposedly makes, don’t give up on practising but change what you are aiming to get from it.
