Most of the time we use only one sense, that is thinking. According to Buddhist psychology this is the sixth sense, but we have other senses which we sometimes neglect. So we can awaken the sense of seeing by looking at things, looking at flowers, looking at little objects, looking at the sky, the clouds. In fact we can develop concentration in this way. I know some meditators who find it easier to concentrate in this way rather than concentrate on the breath, where they can have complete awareness of what they are seeing, and they are fully experiencing the present moment in that situation. And when we see something beautiful we have joy.
In fact in the Buddhist texts there are many references to seeing something beautiful. On one occasion the Buddha was walking with Ananda, his attendant, and at some point he said: Look back, what beautiful scenery we are passing through! There is a section in the Pali texts where it describes how monks and nuns became enlightened, and in that section some of them describe how the beauty of nature was very inspiring, because most of these monks and nuns were living in forests. And sometimes, as we are living in towns, big towns, where we don’t see nature very often, we are losing this sensitivity for appreciating something beautiful, for learning to relate to nature in this way.
