Have you ever seen a ghost or a god? Normally people can't see
things that are too far, near, big, or small. But some people
borrow the power of a ghost or other spiritual being, and gain
spiritual vision. There are also cases of heavenly beings who are
born into the human realm, who still retain some ability to see
ghosts and spirits in the realms below. They can no longer see into
the heavenly realm, nor can they see ghosts and spirits in the
human realm.
I had a student who came here for a beginner's class. She claimed
to have some psychic power. She said that when she was
well-concentrated, she could see into people's past, but I had my
doubts. I asked her if she could see into my past. I have heavy
karmic obstructions, which have their root in past lives, but still
she could see nothing of my past. Why? People are not always reborn
into the human realm. They might be born into a distant world, and
ordinary psychic power would be too limited to see that far. It
would be similar to a person who commits a crime in Taiwan and
moves to New York. The New York police would have no record of the
crime.
The ghostly or deva eye stands at a level between the fleshy and
heavenly eyes. This phenomenon occurs when a spiritual being uses
the eye of a human being as a medium. People who have experienced
this believe that they have been endowed with great spiritual
powers, but it is really the power of the spiritual being at work.
There is a book about a spirit called Seth who used a woman's body
to talk to people in this world. He could only talk through
her.
I have a Dharma brother who has such powers. He was once sitting on
a train, and suddenly he saw all the people sitting around him as
pigs and dogs and other animals. He could see the changes that
these people went through in various past lives, but he could see
no further. This is not really his power, but that of a spiritual
being working through him. I asked him if he could see such things
with his eyes closed, and he answered no, but there are people who
have such powers.
In the sutra Buddha talks about a disciple, Anirudha. He is a good
example of someone who developed the heavenly eye. He practiced
very hard. He sat for days with his eyes open, and he never slept.
Eventually, he went blind from keeping his eyes open. The Buddha
went to visit him and told him not to worry. He said that the
fleshy eye is of little use anyway, and there are better eyes to
acquire. The Buddha explained to Anirudha how to practice, and in a
short time he had the heavenly eye. As he penetrated deeper into
dhyana, his vision became truly vast.
Those who are born in the realm of desire with the heavenly eye,
because of their previous good karma, are always born in heavenly
realms. Those born as humans in the realm of form, must obtain the
heavenly eye through meditation. Normally, human beings cannot see
ghosts, and the ghosts that are here cannot see us. The more
powerful beings in the heavenly realms can see us, but spiritual
beings here cannot. They can sense our existence, but they can't
tell exactly where we are. Only by borrowing an earthly eye can
they see more accurately. An English psychologist who was able to
leave his body reported seeing just this sort of thing; he saw
ghosts and humans, but they could not see each other.
The heavenly eye can observe all manner of beings in the realm of
form: animals, humans, ghosts, spirits, heavenly beings. This eye
can see into the past and future for 500 to 1000 lives. But looking
into the past and looking into the future are two distinct psychic
powers. In the six heavenly realms, the lower realms cannot see
into the realms above them. Why? Because the body becomes more and
more subtle as you ascend into these realms. A being in the highest
heavenly realm can see throughout his realm and all the realms
below. Such a being can see us and know us as if we were specks in
the palm of his hand.
Common people cannot really understand this heavenly eye. It has to
be experienced. Sometimes someone in Canada might be able to see
what's going on in the United States, or someone in United States
can see things in Hong Kong. This is not the heavenly eye at all.
It is still the ghost, or spiritual eye. The heavenly eye, within
its realm, knows what is going on in all places at all times.
