"The all pervading essence of creation, filling all space and interpenetrating all matter. The holder of all unseen events. All things exist first as ideas or thought-forms in the etheric before manifestation into the physical." (SJA)

"Etheric pertains to an environment that is not based on physical reality but still contains form. Many ideas or thought forms in the etheric may become manifest in the physical world." (PoL)

Etheric is the frequency band or octave just beyond the physical octave. Etheric energy or substance vibrates at speeds beyond light velocity and has a magnetic character. (Source: R. Gerber, Vibrational Medicine, Glossary).
