The existence of this astral light can be proved from the fact that certain phenomena can only be explained upon the assumption of such existence, and it is moreover an objcet of direct perception to Adepts. Once let its existence be granted, and also the fact that it concentrates itself more thickly around the brain and nervous system than elsewhere, and you will see that nature has made provision to enable a person to catch the impressions made by others on the astral light.
In thought-reading experiments the best results have generally been obtained from children. The reason of this is that the aura of a child is passive, because it has not generated any active tendencies of its own. This fact can be inferred from the difference in colour between the aura of a child and that of an adult. The aura of a child is milk-white, but in the case of a grown-up person there is always upon this basic colour, another colour as green, yellow, red, &c.

Every thought is accompanied by another physical phenomenon which may be described as an alteration in the nervous fluid. There is intimate connection between nerve-fluid properly so-called and the aura surrounding it. Nerve-fluid has its own aura like every congregation of molecules in nature, even prime ether has its own aura which is âkâsh. Nerve-fluid has its own aura, called the odic aura of the man. All auras have one base, they are all akin to the magnetic fluid in the cosmos. For every thought there is an affection of the nerve currents of the brain or nerve. This implies vibration which is caught up by the astral aura which communicates with the astral fluid with which it is in contact.
This vibration affects the odic aura round the thinker's brain, and is immediately transmitted to the brain to which
