mmmmm.... I really like that imagery of the ocean. It sounds very similar to what Martin Prechtel
www.floweringmountain.com says. He is an Mayan Shaman, and teaches that 'this world' and 'the other world' are like a tree growing in the earth. We are the part of the tree that you can see - the trunk the leaves, the branches. The other world is the part of the tree you don't see - the roots. The roots put the sap in the veins and provides the life. We are not seperate beings between the lives, but we lose our memory of the root world a few months after we are born. It makes me think that the wave in the ocean story perhaps had similarly forgotten what it was like in the ocean world.
One quote from Martin Prechtel that has really been a source of much meditation recently is "Grief is Praise for what we have lost." Much said in those words. I am eagerly awaiting my copy of his CD "Of Grief and Praise".
