What one needs......
.........to directly understand the phenomena is to encounter it first hand. This could be done by an active wish, then some time spent in nature, observing.
If done often and carefully enough, one will experience the phenomena on a small scale, depending upon your belief system. IF you are OPEN to it, chances are you will identify or experience it better when you actually come in contact with it.
Saying it isn't so while staying indoors 24/7 just won't cut it.
