Gil Fronsdal leads a Guided Meditation Dharmette: Noticing. He starts with a story about an extraordinarily ordinary person and how practical noticing is.
Be Mindful, be attentive, if you make mistakes, it's okay.
Gil expounds on a story about his Zen teacher, his first meeting with him and how it became a transformative or pivotal point in his life's experience of becoming a Zen teacher himself. How he characterizes this man as very extraordinarily ordinary, completely at ease and just being there.
He explains how this noticing is a special part of awareness and mindfulness between people. Either you notice others and or people notice you, especially when you are a sort of public figure you ought to behave in a way that because people notice you, to notice your own shortcomings. In Buddhism, the practice is like how you are representing the Buddha and how the Buddha projects his presence.
