to mi its ok la, as long as their teachings are not harmful to
oneself or the others.
there's so many different kind of spirits around that we cannot
see, doesnt mean they dont exist lor, some are hungry ghost, bad
ghost, good ghost, powerful ghost, and those who hang around dont
want to recarnate.
anyway if the spirit(or so called god) is willing to help you in
life in watever ways, good la, but make sure it helps you
willingly&unconditonally and not in exchange for your soul or
watever la.
