If I have a glass of water standing upon a table, the glass and the table, being of physical matter in the solid state, are interpenetrated by astral matter of the lowest subdivision.

The water in the glass, being liquid, is interpenetrated by what we may call astral liquid--that is, by astral matter of the sixth subdivision; whereas the air surrounding both, being physical matter in the gaseous condition, is entirely interpenetrated by astral gaseous matter--that is, astral matter of the fifth subdivision.
But just as air, water, glass and table are alike interpenetrated all the time by the finer physical matter which we have called etheric, so are all the astral counterparts interpenetrated by the finer astral matter of the higher subdivisions which correspond to the etheric.

But even the astral solid is less dense than the finest of the physical ethers.
The man who finds himself in the astral world after death, if he has not submitted to the rearrangement of the matter of his body, will notice but little difference from physical life.

He can float about in any direction at will, but in actual fact he usually stays in the neighbourhood to which he is accustomed.

He is still able to perceive his house, his room, his furniture, his relations, his friends.
