I know a Seer is someone with a silenced mind. And I believe you've said that many psychics fall into the trap of channeling their own soul, and also that the information they receive through the pineal gland is inverted, thus they can have trouble interpreting it correctly. Please could you tell us a bit more about the difference between a Seer, a Clairvoyant and an Oracle?
Let's start by looking at the topic of predictions. There's a lot of distortion spoken with a great pretext of "authority", being peddled out in the world today as man grasps for certainty in an uncertain world. Native Americans call these "revelations", wishions — 'they wish they were visions'. In other words, they are fabrications of the mind. Every action of every person changes the future outcome. Sobriety can only clarify the past and its resulting present outcome — but not the future. It is an extremely difficult thing to predict the future of any individual, or the planet or of humanity.
It requires a highly skilled Seer be able to see the intricacies of the currents of many lifetimes in order to make a prediction of future possibilities.
Seers work with long term predictions because they can see the currents of the flow of time. Clairvoyants get impressions of possible short term developments, but aren't able to see their relevance in the person's life's story, or destiny. So as you point out, they don't interpret what they see well.
Oracle has to be properly defined. I've used this term in the past to indicate those who have a continual stream of information coming in. But technically it's not correct. An oracle uses a person or an object as though they are Seer's Stones. They can get information by viewing the universe through the 'lens' of another life form.
A Seer that has honed his or her skills with discipline and in the silence of the mind over many lifetimes, can combine these three methods and predict with amazing accuracy.
