"Mirror, mirror, who is the most beautiful?"
remember the witch from snow white's question?

Since time immemorial, witches, sorcerers and wizards have generally used mirrors, honing metals and water sources that reflect, to predict the future. Even snow white witch uses it. What is an omen? It is the vision of a fact of the future, the present or the past, sent by spirits of another plane existential, concentrating within objects look like a mirror. Mirrors that have the power necessary to reflect these views are called mirrors black.

As we said before, blacks mirrors are not the only way to be an omen, also used sources of water, balls of glass, shiny metal, etc.

Of all the methods omen, which I prefer and gave me better results, it is the black mirror. They usually have a great magical power, although it shall not abuse them so they don't lose it and give them time to replenish their energies. It is also vital strength and concentration with the wizard or witch who uses it, and the practice that has to read in the mirror.

The black mirror becomes, for the magician expert in the window to the universe and the spiritual world. It can give you the vision of past lives or of facts that are about to occur. You can give you answers to questions you have, or show you a guide to entering the world of the most there.
They must understand, my readers, that the omen takes a bit of practice to begin to develop it.

Astral Vision
What is an Astral vision? It is the ability to see inside the Astral planes in a black mirror. For some people, who are naturally inclined to possess this gift, it can be normal and easy. For others, it can take months to reach a vision. Clean the mind and achieve a clear concentration is vital to achieve the vision.
It can be used for many purposes in the magical divination. For those willing to study high magic, you should know that the black mirror is used in the "triangle of Solomon" to exorcise the demon or celestial bodies. Spirits are not manifested in its physical form, but as a vision in the mirror that the sorcerer is able to recognize in the astral plane thanks to the black mirror.

It is important: many newbies will not see the spirits or see them by a fraction of a second, or "believe to see it". It is difficult to have the powers necessary to obtain a clear and lasting vision of the spirit, and only can be achieved with serious and constant practice. Those who just begin, I recommend spending a good time (between half an hour and now) meditating with staring in the mirror, and your mind clear.

I recommend them to have patience with the black mirrors. The art of divination is hard, but not impossible.
