Yesod is the ninth Sephirah of the tree of life completing the triad of Yetzirah corresponding to the sixth day of creation. This stage is the integration point of energy and its contexts. The ninth stage of Yesod is where the emanations of the entire tree of life are adopted through the cosmic life force energy. The Sephiroth of the tree are charged with the life force of Yesod and with this, the tree has the power to influence Malkuth, the sensual and physical world that we experience. The life energy of Yesod linking the nature of mind and matter is known as the Akasha in the East, or the Astral Light in western esotericism. Everything that has form in the physical is evolved out of the Astral Light.
Yesod is associated with the Soul with the power to contact, and communicate with the outer reality (represented by the Sephirah of malkuth). The foundation (Yesod in Hebrew) of a building is its “grounding,” its Union with the earth (Malkuth)(Gal Einai, 2014). This Sephirah corresponds to the reproductive organ in the symbolism of the human body. The Nephesh: Animal Soul is placed on this seperah. The Nephesh is the part of the soul\mind that deals with sex drives, apatite, and survival. Its the animal nature of man that we share with the animal kingdom. Its planet in the physical world is the Moon: all Lunar deities can identify with Yesod. The lunar cycles and fazes play an important role on earth with tides and physiological functions of plants and animals. Yesod’s virtue is independence and vice is idleness.
Yesod equates with the sacral chakra, the chakra of sexual energy and creativity. The Astral Light is built from the same electro-magnetic current that runs through each person’s Etheric body. Its magnetisism is the dynamo of sexual energy also known as the Kundalini.
