Extract from Wikipedia - Akasha (or Akash, Aakaashá) is the Sanskrit word meaning "aether" in both its elemental and mythological senses. Akasha is the omnipresent incontrovertible transcendent eternal source of all energy, the realm of promise, potential, paths to be walked and the primal source that creates and nourishes the other four elements, Fire, Earth, Air and Water. Akasha is all directions, East, South, West and North and all seasons, Spring, Summer, Autumn and Winter. It is not limited to three dimensions, Length, Width, and Depth or Height, but is made up of infinite ones comprising all possibilities of movement, both material and spiritual.

Meaning in different philosophies

Hinduism In Hinduism Akasha means the basis and essence of all things in the material world; the smallest material element created from the astral world. It is one of the Panchamahabhuta, or "five great elements"; its main characteristic is Shabda (sound). In Hindi and Gujarati, the meaning of Akasha is sky. The Nyaya and Vaisheshika schools of Hindu philosophy state that Akasha or ether is the fifth physical substance, which is the substratum of the quality of sound. It is the One, Eternal, and All Pervading physical substance, which is imperceptible. According to the Samkhya school of Hindu philosophy, Akasha is one of the five Mahabhutas (grand physical elements) having the specific property of sound.

Jainism Akasha is space in the Jain conception of the cosmos. It falls into the Ajiva category, divided into two parts: Loakasa (the part occupied by the material world) and Aloakasa (the space beyond it which is absolutely void and empty). In Loakasa the universe forms only a part. Akasha is that which gives space and makes room for the existence of all extended substances.

Buddhism In Buddhist phenomenology Akasha is divided into Skandha, Desa, and Pradesa. The Vaibhashika, an early school of Buddhist philosophy, hold Akasha's existence to be real. The Western religious philosophy called Theosophy has popularized the word Akasha as an adjective, through the use of the term "Akashic records" or "Akashic library", referring to an ethereal compendium of all human knowledge.

Modern Paganism It is believed by many modern Pagans that the Akasha, Spirit, is the Fifth Element. Scott Cunningham describes the Akasha as the spiritual force that Earth, Air, Fire, and Water descend from. Some also believe that the combination of the four elements make up that which is Akasha, and that Akasha exists in every living creature in existence; without Akasha, there is no spirit, no soul, no magic. The Five Elements are worked with to create positive changes on earth. This is done through meditation to bring about beneficial changes in one’s life. Akashan spirituality is holistic. Practitioners learn to maintain mental and physical health through meditation, exercise, ritual and diet. They are expected to have a profound commitment to their life path. The upward point of the pentacle, the pentagram or five pointed star within a circle, represents Akasha. The others represent Fire, Earth, Air and Water. While Earth is considered "north"; Fire is "south"; air is "east"; Water is "west", while Akasha is "center".
