Lifestream
The stream of life that comes forth from the one Source, from the I AM Presence in the planes of Spirit, and descends to the planes of Matter, where it manifests as the threefold flame anchored in the secret chamber of the heart for the sustainment of the soul in Matter and the nourishment of the four lower bodies.
Also used to denote souls evolving as individual “lifestreams” and hence synonymous with the term “individual.” Denotes the ongoing nature of the individual through its cycles of individualization.
