There are Christians and Muslims who denounce mysticism as being dangerous while there have also been Christian and Muslim mystics. Transformatsiya is a fictional religion created from the influence of Judaism, Christianity and Islam and was formed through mysticism and contact with the spiritual being Tanisha who revealed previous religious teachings to the early followers. Part of the religious teachings include how to safely understand the influence of the spirit world.
Under the religious Zakon Law, mysticism and occult rituals are restricted to sanctioned mystics because ignorant exploration of the spirit world is incredibly dangerous and is likely to lead to demonic possession or influence.
Unsanctioned mysticism is punished by mandatory intervention from social workers of the PKVD, court order to see a psychiatrist who is a sanctioned mystic, or in extreme cases confinement to a mental hospital where they would receive spiritual guidance.
All the prophets up to Tanisha (who is a spirit) are considered mystics who received divine revelations from God or his messengers through the spirit world.
So it seems like there is a spiritual world, but that the religion doesn’t conform to the spiritual world, which creates a conflict.
It’s mainly intended to be accurate for describing the path toward salvation, especially the first salvation that happens after death. Tanisha mentions the day of judgement, but this is based on faith. There’s more stuff in the holy book of Transformatsiya that describes various “islands” in the Shadow Realm. Everyone has their own personal island that exists while they are alive. Sin causes it to become a form of Hell. Atheists get trapped on the beach of the island until they accept the existence of the spirit world. Richard Dawkins is still trapped on the beach because he has faith that he’s trapped inside a simulation.
Transformatsiya is largely based around the idea of achieving peace though following the path of God and that people should be servants and messengers of God.
