The journey through the desert acts as a potent symbol of the journey through life and people’s pursuit of their calling. It is also reminiscent of the journey of the Magi to witness the birth of divinity on earth:

After Jesus was born in Bethlehem in Judea, during the time of King Herod, Magi from the east came to Jerusalem and asked, “Where is the one who has been born king of the Jews? We saw his star in the east and have come to worship him.” Matthew 2:1-2

The Magi had links to alchemy.  They were "wise ones", Zoroastrian philosophers, magicians or astrologers, and as such were believed to be in possession of occult secrets.
