You may ask your question @Ignited! As @Thierry007’s question is not necessarily a question for divination.
My answer to this is no, as that is not how this works in my view and experience. The idea that the future is completely random and when we do divination it “locks” that future into place exists in a worldview where everything is random. However, in my experience things are not random at all.
If everything was random then traditional Natal Astrology and Electional Astrology would not work. However, they very much do. They all work whether a person believes in them or not. Everyone is subject to a higher spiritual cycle that moves this material world, whether they are aware of it or not, or if they are willing or not. You can see this for yourself, just with the planetary hours. People act and feel appropriately to the Planetary Hour. In the Hour of Mars, people are more angry and argumentive, and have the more will to get things done at times. In the Hours of Venus and Mercury, people are more loving and talkative. I, and others who Practice this, find this to be very true. Even the animals play and fight etc. According to the Planetary Hours. Hermes Trismegistus famously said in the Emerald Tablet “As Above, So Below”, which is to say, we move in line with the stars and planets above.
In fact, divination itself would not work if everything was random (according to Plotinus).
And this is why I never ask for birth times, names, or pictures when doing a Geomancy or Tarot reading for someone. I don’t need anything to “connect” to the person, as this is not about “energy”. This works through the harmony and synpathy between all things in the cosmos. As Plotinus says, the entire cosmos is one Unified Living Being. So, as Plotinus says, divination works in such a way as how a Physician looks at one part of the body and is able to gather information about another.
Now, there are times when we exert free will, and this power comes from the Soul. However, traditionally it is seen that the Spirit (the intermediary between the Body and Soul) is under the influence of the Stars and Planets (however, I do not necessarily mean the material stars and planets), and Spirit is linked to emotions. When are we not acting from our emotions or passions? For this reason, exerting free will is exceptionally rare.
