Yes that is right, magick is not all powerful as we see, it can not change everything in the world, and usually when it is done it takes time for what is requested to be granted.
So, we must keep in mind, that you have your personal fate, but you are working within the fate of your household, your work, city, your country, and your country is affected by the fates of everything that influence it. So, there are very well times when magick can not overcome these things.
The extent of these things in our lives is great, so great that often times already at the moment of a person’s birth, we can see how they will die from the Astrological factors present at that moment. The 8th House of the Heaven, its Sign and its Lord reveals details on this, and in the Medieval Ages.
“Three Wise Women
by that well
under that tree.
Urth is named one,
Another is Verthandi,
the third is named Skuld.
They carve men’s fates,
they determine destiny’s laws,
they choose the lifespan
of every human child,
and how each life will end.”
Völuspa, Stanza 20, Jackson Crawford translation.
Already from the point of one’s birth, these things are known, and this has been known by many cultures in ancient times.
So truly, there are many who live life without ever significantly exercising free will to the point where the circumstances of their death never change. It was a common question for Medieval Geomancers how long one will live and how they will die as well, but the very Heavens show this at that time of birth.
It is very pleasing to the ego to believe we are always exercising free will and have the capability to anything in life (see, the Holy Guardian Angel), but in practice this is not the case.
However these things are not said to depress you or anyone else, but rather there is a great spiritual harmony between everything in the world. In practice, we can see this every day, and it makes magick and divination and all such things possible in our lives.
So, continue as you will to seeking a good path in life. If you can obtain the visa, it will be obtained, and if it can’t, then simply move to another path that is good.
It may even be more beneficial to use magick to seek guidance on what to do, rather than insisting this visa is the only way to obtain what you want in life.
