Hi there again
I am not actually a Buddhist myself, although I do have some loose involvement with them. The walk was organised by some people from the Buddafield cooperative (who run the festival and cafe of the same name). Some of Buddhafield's meditational retreats have a strong nature / sacred landscape theme. This walk was one of these.
Whilst Buddhist's don't actually celebrate the summer solstice as such, some of there rituals do take place at full-moon. Although I don't know much about this myself.
I enjoyed the walk, as it was a great opportunity to go to the solstice with a group of like-minded people. Some of whom apart from being Buddhists / Buddhist minded or even non-Buddhist, have an interest the native traditions of the British Isles. As for the solstice, then why not? Many other groups individuals are there. The Kumbh Mela in India attracts many different traditions and groupings who all take a symbolic dip in the river. In many ways I believe the solstice at Stonehenge will grow in its own way. Touching the Heel Stone for example is just one of these things that will grow to be part of the occassion. I must post some photos.
