Go to Avebury and park in the car park. Walk the short walk past the ice cream van and the cricket field to the stones. Nothing much except staring without understanding as one of the crowd.
Walk the long walk from the car park. Follow the river towards WKLB with Silbury on your right. Walk towards the Sanctuary and take the lane to the beginning of the Avenue. Slowly and reflectively follow the Avenue to the stones. Everything falls into place and you get a brief flash of insight and connection to the whole.
Same thing with mountains - go by horrible 4WD as close as you can. Climb up and climb down - big macho conquering thing
Walk in through the landscape seeing the mountain gradually increasing in size over several hours. Become part of the landscape and then climb with no thought of conquest or record breaking. Just being there is enough. Communion.
Key elements? Time - we rush experiences far too much
Physical effort and mental contemplation come from taking a longer time
And switch of the bloody mobile phone!
