Astral Body

Astral Body is a subtle body that can serve as vehicle of consciousness. In her book Isis Unveiled, H. P. Blavatsky says:

The designation astral is ancient, and was used by some of the Neoplatonists. Porphyry describes the celestial body which is always joined with the soul as “immortal, luminous, and star-like.” The root of this word may be found, perhaps, in the Scythic aist-aer — which means star, or the Assyrian Istar, which, according to Burnouf has the same sense.

H. P. Blavatsky used the term frequently to refer to the second principle in Man or linga sharira:

Astral Body, or Astral “Double”. The ethereal counterpart or shadow of man or animal. The Linga Sharira, the “Doppelgäinger”. The reader must not confuse it with the ASTRAL SOUL, another name for the lower Manas, or Kama-Manas so-called, the reflection of the HIGHER EGO.

However, in some occasions Mme. Blavatsky also applied this term in a more general way, saying that "there are various Astral Bodies". For example, she wrote: "A more important kind of Astral Body is the Māyāvi-Rūpa, or illusionary Body, and this is of different degrees." She also talked of the astral body as being constituted by "the lower manas and volition, kama".

Since the linga sharira cannot go far away from the physical body, it is to these other kinds of astral bodies that Mme. Blavatsky was probably referring in the following passage in Isis Unveiled:

In our sleep the astral body is free and can, by the elasticity of its nature, either hover round in proximity with its sleeping vehicle, or soar higher to hold converse with its starry parents, or even communicate with its brothers at great distances.

According to Besant and Leadbeater

Annie Besant felt the nomenclature for the subtle bodies needed adjustment to use terms in unequivocal ways. She decided to call H. P. Blavatsky's linga sharira "etheric double" and the kamic body as "astral body":

On looking at a man's lower bodies with astral vision, the etheric double (Linga Sharīra) and the astral body (kâmic body) are seen interpenetrating each other, as both interpenetrate the dense physical, and hence some confusion has arisen in the past and the names Linga Sharīra and astral body have been used interchangeably, while the latter name has also been used for the kâmic or desire-body. This loose terminology has caused much trouble, as the functions of the kâmic body, termed the astral body, have often been understood as the functions of the etheric double, also termed the astral body, and the student, unable to see for himself, has been hopelessly entangled in apparent contradictions. Careful observations on the formation of these two bodies now enable us to say definitely that the etheric double is composed of the physical ethers only, and cannot, if extruded leave the physical plane or go far away from its denser counterpart; further, that it is built after the mould given by the Lords of Karma, and is not brought with him by the Ego, but awaits him with the physical body formed upon it. The astral or kâmic body, the desire-body, on the other hand, is composed of astral matter only, is able to range the astral plane when freed from the physical body, and is the proper vehicle of the Ego on that plane; it is brought with him by the Ego when he comes to re-incarnate. Under these circumstances it is better to call the first the etheric double, and the second the astral body, and so avoid confusion.
