I agree with AEN and Thusness... pls don't try it. Practise the
dharma at our own pace, no matter how slow that may be we must be
patient. Many other non-Buddhism practices or mediums also hv third
eye or similar to that, but as AEN mentioned, they may not
have Wisdom or insight. Many are just " gui3 yan3". There's
no short cut to attain " tain1 yan3, fa2 yan3, hui4 yan3".
But of cos, pls consult your guru further on this matter.
As for images of ghosts or spirits, well, believe me, most of us
would not want to see them. I have a friend who is constantly
seeing such things since his teens. I do not even feel like
describing it to you.
He's not a Buddhist, but after he took my advise to chant the
name of Buddha whenever such ghostly entities appear( usually it
was very sudden, and sometimes dangerous moment like when he was
driving on the highway), he could stay calm and the entities would
disappear or fade away. So, you see, by just chanting Amituofo
which is one of the many ways of practising, one could avert harm
and protect oneself in a way or another. Be patient.
If best you ask him to gui yi also..
