Let's put it this way, when you die, supernatural powers
are not going to be of much use. It is like money, beauty,
fame etc. All these supernatural powers are transient.
And also, without wisdom, supernatural powers are not consistent
and not 100% within one's control, also they can fade away when
certain conditions are no longer there. Basically, it is like
good luck... sometimes have it, sometimes no.
One teacher once said, if you are seeking psychic powers, just
go and knock your head on the wall and die. When you are in
the bardo, you have alot of supernatural abilities eg. knowing
others thoughts etc... of course this is just humour... don't take
it seriously hor...
When we practice, whatever form of Buddhism, the minimum
criteria is confidence in facing death. I myself feel that this is
the benchmark and thing to work towards... of course i am not
saying Dharma people are so life-denying and only focus on death...
but this is a very 100% sure future situation we have to face, so
while we treasure life and enjoy it, if we have some sense, we
should also make sure our enjoyment continues longer into the
future than only this life...
psychic powers is like a short-lived kick... if you have it,
then what next? One should always think like that. With
afflictions in one's mindstream, no matter how external changes, we
will always be suffering... therefore, you should think twice about
what you wish for... or you may simply be getting a very lousy
bargain for all your time, life and energy invested.
