An understanding of the houses is fundamental to accurately interpreting a geomantic cast and the resulting figures - the geomantic tableau. The twelve geomantic houses are borrowed from medieval astrological practices.

Any question that you can think of can be assigned to one of the twelve houses. For example, questions about traveling are assigned to the ninth house; questions about marriage are assigned to the seventh house; questions about health are assigned to the sixth house; questions about money are assigned to the second house. And so on.
