It is also possible for Thomas to be caught by nearby
spirit.
There is a real story about a lady who went to a cave to meditate
with friends a few months ago. One day, she just disappear to
nowhere. Her friends searched thru the whole cave but just couldn't
find her. Later on, they went to ask a medium to help. The medium
said that she was caught by mountain spirits. In fact, these is a
construction site nearby and during the construction, the worker
throw away a lot of rubbish to the cave which made the spirits
living there very angry.
Her friends also went to ask a tibetan monk for help.
Both the tibetan monk and the medium who is not a buddhist said
that the victim was caught by more than ten spirits and was in a
very wet place. She must be rescued by tomorrow noon else chances
of surviving will be diminished.
While the medium was negotiating with the spirits to set the victim
free, her friends and the tibetan monk start chanting (Da Bei
Zhou). After sometime, the medium said that bodhisatva has come to
her rescue. The lady was then discovered by them at a hill where a
normal human can never climb till that high. At the same time, the
fire engine has arrived and bring the lady back.
According to what the tibetan monk has said, due to the metta of
the bodhisatva, the mountain spirits have all converted to buddhism
and become dharma protectors.
It is very important to take note that, don't anyhow go to a remote
place to do meditation unless your spiritual cultivation has
reached certain level. It is also beneficial to us to do chanting
or mantra frequently, so dharma protectors will always protect you
from time to time.
