The garden is again a symbol. The story of the world starts with the garden, the Garden of Eden, Adam and Eve, and life was eternally beautiful and blissful. The garden is the beginning of existence.
And then Adam and Eve were thrown out, or threw themselves out, by eating the fruit of the Tree of Knowledge.
The moment you become knowledgeable you lose innocence. And innocence is the garden. In innocence, flowers bloom. In innocence, fragrance is released. In innocence, all is bliss. The garden is a symbol for innocence. And since Adam and Eve left the garden, man has been searching for the garden again and again.
The teqir, or the school of the Master, is called the garden of the Master - because with a Master you start vomiting the fruit of the Tree of Knowledge. The Master is nothing but a process of taking out all the poison of knowledge from your system so that you can become innocent again. And when Adam is innocent, Adam becomes Christ. He enters the garden again - paradise lost, paradise regained....
