it

As we explore together the virtual world that floats on the edge of this material life, the many imaginative territories you inhabit bring back another reality. I catch images of my own childhood wanderings through Narnia, the land of Hobbits, and Mowgli’s jungle. All these are deep pleasures which combine all my senses and momentarily transport me into another dimension of living.
If I were to bring it all together I would say that among all the misery, fear, injustice, and pain, I hope you will not forget moments when all this fades away into periods of innocent joy. It is when we bring all our powerful senses together, perhaps in a moment in the garden of earthly delights that we triumph over despair.
