He is in every way the same man, minus his physical body; and his happiness or misery depends upon the extent to which this loss of the physical body affects him.
If his longings have been such as need a physical body for their gratification, he is likely to suffer considerably.

Such a craving manifests itself as a vibration in the astral body, and while we are still in this world most of its strength is employed in setting in motion the heavy physical particles.

Desire is therefore a far greater force in the astral life than in the physical, and if the man has not been in the habit of controlling it, and if in this new life it cannot be satisfied, it may cause him great and long-continued trouble.
Take as an illustration the extreme case of a drunkard or a sensualist.
Here we have a lust which has been strong enough during physical life to overpower reason, common sense and all the feelings of decency and of family affection.

After death the man finds himself in the astral world feeling the appetite perhaps a hundred times more strongly, yet absolutely unable to satisfy it because he has lost the physical body.

Such a life is a very real hell--the only hell there is; yet no one is punishing him; he is reaping the perfectly natural result of his own action.
