ANCIENT CULTURES and PANORAMIC SENSING
Some ancient cultures recognised the possibility of using the senses in their panoramic capacity.
Among the Australian aborigines it is called Dadirri : "Simply sit and look at and listen to the earth and environment that surrounds you."
But in the explanations i have read, this is always explained with some sort of focusing on specific things. "Focus on something specific, such as a bird, a blade of grass, a clump of soil, cracked earth, a flower, bush or leaf, a cloud in the sky or a body of water, whatever you can see."
I believe this 'focusing on specific things' is a modern development.
Tao and Zen
In Taoist and Zen literature, i believe it is meant by the term 'just sensing', ... but this could also mean focusing with the senses.
I am sure it is the original idea behind the Taoist and Zen practice of "Staring at Walls". A blank wall is ideal to focus on, as a bridge to panoramic seeing.
The Zen idea "seeing without looking – hearing without listening" expresses it very well. (I think it's a quote from Bodhidharma but from where?)
Buddha's Middle Way
Buddha's Middle Way is a way between the two extremes of sensual indulgence and sensory withdrawal. Panoramic sensing is a way of using the senses which fulfills these requirements perfectly.
