A lot of emphasis in the early stages of the Qabalah focuses on the state of the subconscious and exploring how the conscious, subconscious and higher mind (intuition / sixth sense) all work together.
The spiritual journey of the Qabalah often begins in the sephirah Malkuth on the Tree of Life. Malkuth represents our physical body as well as the private world we have created for ourselves. Behind Malkuth sits the sephiroth Yesod. Yesod represents our subconscious and governs our emotional reactions and responses which in turn affects the way we behave and operate on the Earth plane. The power of the subconscious is awesome. The mystical teachings of the Qabalah can help us rein in that power and change the programme so we are can break free from preconditioning and remain in control rather than being controlled by our subconscious triggers.
