Meditate deeply on the Heart Temple of the center of the Earth. Meditate on the Genie of the Earth whose name is Chamgam. Ask him to put you in contact with the Gnomes that inhabit the entrails of the Earth.
Call the Genie of the Gnomes. That Genie is called Gob. Fall asleep concentrated on that Genie. Vocalize the mantra IAO.
Very deep meditation intelligently combined with sleep will enable you to enter the Elemental Paradises of Nature.
Every alchemist needs to work with the elementals of Nature.
