When you have a mountain top experience and you see something change before your eyes it can be a moving spiritual experience. Transformation or transfiguration is something that blows your mind in such a way that you kind of bask in the light that shines from it all.
The Transfiguration of Jesus is an event reported in the New Testament when Jesus is transfigured and becomes radiant in glory upon a mountain. In many Christian traditions this event is celebrated yearly as a feast day.
Encountering the divine in such a way adds comfort, peace and a desire to rest there. However that is not where life is meant to be lived. You have to take the experience of the mountain to sustain you and keep you through the dark times in the valley below.
No matter your faith there are moments and places that give you comfort and renewal. Celebrate those times when you find yourself transformed a little and may you find comfort to get you through life.
