Thus a man who frequently feels high devotion soon comes to have a large area of the blue permanently existing in his astral body.
When the rush of devotional _feeling_ comes over him, it is usually accompanied by _thoughts_ of devotion.

Although primarily formed in the mental body, these draw round themselves a large amount of astral matter as well, so that their action is in both worlds.

In both worlds also is the radiation which was previously described, so that the devotional man is a centre of devotion, and will influence other people to share both his thoughts and his feelings.

The same is true in the case of affection, anger, depression--and, indeed, of all other feelings.
The flood of emotion does not itself greatly affect the mental body, although for a time it may render it almost impossible for any activity from that mental body to come through into the physical brain.

That is not because that body itself is affected, but because the astral body, which acts as a bridge between it and the physical brain, is vibrating so entirely at one rate as to be incapable of conveying any undulation which is not in harmony with that.
The permanent colours of the astral body react upon, the mental.
