In the beginning God gave man a Garden of Eden. However, man, being man, soon polluted this garden and its glories are lost to him until, by the "sweat of they face" (his own efforts), he is able to reconstruct it. This is one of the two main purposes for life on Earth. The other is the individual's personal spiritual development, the wisdom and power of which are to be used to recreate the lost Garden.
When we discover an untouched mountain meadow or virgin forest, we realize that the Garden of Eden is not really lost; it s still here, but, with eyes that will not see, we are blind to live the life necessary to make use of them.
By his inability to understand the Divine Laws of his being,
and even more so, by his determination to not follow them even
if they are understood, man has created for himself a Hell out
of what is really an earthly Heaven. It is only our perversity
that turns beauties of God's creation into the man's concrete
and asphalt jungles.
