I know a man casually and sometimes we share a moment or two. We often discuss the joys of nature. He is an avid birder and will spend hours walking in the countryside.

Sounds, sights, textures and smells of the natural world can be so entrancing that one may feel completely absorbed into the surroundings.

This man described such a sensation as becoming invisible-disappearing for a time.

During one of those moments he was standing in an open meadow lost in the sweet lilting of songbirds nearby.

Suddenly a deer came rushing toward him and brushed his side.

It was as if he hadn’t been standing there at all.
