From Vagueness to Clarity: Developing Inner Attention
Simply to see a bus or a tree requires zero attention. To observe them—their colour, shape, and so on—requires directed attention. You see hundreds of buses and trees every day but do not observe them. It is all a vague, confused picture. In the same way, your inner life is a vague, confused picture. You do not observe it, but you are in general aware of it, as you are of buses and trees.
