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. Dogen-zenji, the founder of our school, always emphasized how important it is to resume our boundless original mind. Then we are always true to ourselves, in sympathy with all beings, and can actually practice.
