I am sure that oracles can heal, especially if the oracle is legit and taking trance of an enligtened being such as Setrab, Dorje Shugden, etc. I have seen it with my eyes. I heard that Gangchen Rinpoche was also healed by an oracle in trance when he was really sick at one point. So definitely, oracles can heal when taking trance of an enlightened being.
Of course, as what Rihanna said, the person has to have the merits to receive such a great honour, but it definitely does not mean that they are protected forever. Merits run out, karma catches up, that's the way of life.
With response to what Wisdom Being said:
"Oh dear, this video appears to have been removed by the user. What a pity - i am fascinated by oracles and wanted to take a look. I guess I should come back to the forum more often LOL
In any case, how do oracles heal people? If people have the karma to be sick, can the protector deity change that karma by alleviating or even curing the illness? Or is the answer that the sick person has the karma to meet the oracle to get healed? I remember reading somewhere that Buddha said that he could not remove someone's negative karma, so can the protector deities change people's karma? I'm curious what people think."
I guess the merit lies in the hands of the person in that they have the chance/karma/fate/destiny to be healed by the oracle. The Buddha cannot take away what we created and deserve, but through our actions and merits gained, I guess a Buddha or one's guru can lessen the negative karma. It is because of one's blessings from the guru that one is able to meet an oracle..so the blessing lies in one's samaya with one's guru?
Anyways, I stumbled upon a post on oracles that I thought was excellent.:
