Irritability is shown by the presence of a number of small scarlet flecks in the astral body, each representing a small angry impulse.
Jealousy is shown by a peculiar brownish-green, generally studded with the same scarlet flecks.

The astral body is in size and shape like those just described, and in the ordinary man its outline is usually clearly marked; but in the case of primitive man it is often exceedingly irregular, and resembles a rolling cloud composed of all the more unpleasant colours.
When the astral body is comparatively quiet (it is never actually at rest) the colours which are to be seen in it indicate those emotions to which the man is most in the habit of yielding himself.

When the man experiences a rush of any particular feeling, the rate of vibration which expresses that feeling dominates for a time the entire astral body.

If, for example, it be devotion, the whole of his astral body is flushed with, blue, and while the emotion remains at its strongest the normal colours do little more than modify the blue, or appear faintly through a veil of it; but presently the vehemence of the sentiment dies away, and the normal colours re-assert themselves.

But because of that spasm of emotion the part of the astral body which is normally blue has been increased in size.
