ear very small, like those on a distant stage, but
in spite of their diminutive size they are as clear as though they
were close by. Sometimes it is possible by this means to hear what is
said as well as to see what is done; but as in the majority of cases
this does not happen, we must consider it rather as the manifestation
of an additional power than as a necessary corollary of the faculty of
sight.

It will be observed that in this case the seer does not usually leave
his physical body at all; there is no sort of projection of his astral
vehicle or of any part of himself towards that at which he is looking,
but he simply manufactures for himself a temporary astral telescope.
Consequently he has, to a certain extent, the use of his physical
powers even while he is examining the distant scene; for example, his
voice would usually still be under his control, so that he could
describe what he saw even while he was in the act of making his
observations. The consciousness of the man is, in fact, distinctly
still at this end of the line.

This fact, however, has its limitations as well as its advantages,
and these again largely resemble the limitations of the man using a
telescope on the physical plane. The experimenter, for example, has no
power to shift this point of view; his telescope, so to speak, has a
particular field of view which cannot be enlarged or altered; he is
looking at his scene from a certain direction, and he cannot suddenly
turn it all round and see how it looks from the other side. If he has
sufficient psychic energy to spare, he may drop altogether the
telescope that he is using and manufacture an entirely new one for
himself which will approach his objective somewhat differently; but
this is not a course at all likely to be adopted in practice.

But, it may be said, the mere fact that he is using astral sight ought
to enable him to see it from all sides at once. So it would if he were
using that sight in the normal way upon an object which was fairly
near him--within his astral reach, as it were; but at a distance of
hundreds or thousands of miles the case is very different. Astral
sight gives us the advantage of an additional dimension, but there is
still such a thing as position in that dimension, and it is naturally
a potent factor in limiting the use of the powers of its plane. Our
ordinary three-dimensional sight enables us to see at once every point
of the interior of a two-dimensional figure
