For me this image personifies our lives... We start in the lake, swimming around for advice and sense in this world... Then once we have matured, we climb out and start seeing the depth of our lives.
Also, the beauty and charm of our lives... Then we can either embark on our jorney in the forest.... We can either get tangled and lost in the forest, in a state of bemusment and confusion of our lives..
Or however, we can remain strong and climb above the forest, and keep on climbing; until we reach the heights of our life. Like the summit of a mountain, we thus reflect on our journey; and the purpose of our being... We look down, still wondering above us... Constantly wondering...
(Sorry I raped the elipsis, and went off on a tangent)
