The big challenge sometimes is to not be distracted. The mind is clear for a few seconds. Next, the mind clouds over. It gets swept away into a mental image, memory, fantasy or some wishful thinking, or into a hazy, soft cloud of dullness. The mind often is lazy. It looks at things and attaches mental labels. Someone shows you a picture. You say, “Oh, a picture,” without actually seeing the picture. You walk past trees. You’re vaguely aware of trees along the street. The trees melt into a generalized mental blur, the label “trees”, so that one barely notices the trees. One’s eyes might be directed towards a tree without actually seeing the tree. The word tree might flash in mind, but does one actually see the individual tree with its wealth of sensual qualities?
