Yesod, Hebrew: יסוד “foundation”, is the 9th sephirah in the kabbalistic Tree of Life, which is located below Hod and Netzach, and above Malkuth. It can be seen as the vehicle from one thing or condition to another (the power of connection).
The consciousness of Yesod, is often associated with the moon. It is the realm of precognition, and the unconscious mind. It is believed to be the place for observing the cycle of life, seasons, and all experience – its lessons come with the understanding of life’s permanent impermanence, and the value of change.
According to Wisdom’s Door:
Because Yesod is a sphere of the unconscious mind, it also is the place of psychic talents and skills. Psychic ability is the function of the subconscious mind. By visiting Yesod you can stimulate these latent abilities and bring them more to the forefront of your consciousness, where you can use them more directly.
The trap with Yesod is becoming too content with yourself and your life to the point that you feel no more learning or changing is needed. You become too idle. Contentment is a powerful place to be when you can use this feeling level and propel yourself forward to greater heights in your evolvement. So if you find yourself becoming idle with your life or because of your visits to Yesod, plan to drop by the sphere of Kether where you can touch the energy of unrestrained manifestation power and help to convert stagnant contentment to dynamic contentment.
The Cherubim work in Yesod. They are the angels of Light and Glory and they also are the keepers of the Akashic records. The Akashic records are the complete human record of the past, present, and future. Now it is important to note that while the Cherubim are most often found here in Yesod and they are the keepers of the Akashic records, the Akashic records are not normally kept in this sphere. However through your contact with the Cherubim you can gain access to the Akashic records if the need is worthy and great enough.
Archangel Gabriel appears here as a tall thin male (or sometimes female) wearing a robe. He is compassionate, gentle and loving. He has a strong mind and intellect. He is a good source to seek out to understand why something is happening in your life, when the source of the problem is still hidden from you or lodged in your unconscious mind. He is a master teacher of advanced out of body travel to places like out of the solar system, time travel, and into other realities and probabilities. Also he is an excellent dream counselor and can often help you to understand what your dreams mean. Seek Gabriel out when your needs are personal and specific. Otherwise you may not notice Gabriel in this place, as it is filled with lots of strong imagery and the unconscious elements of your own mind.
