There are many methods for a wizard to reach the Spirit Realm once they've met the standards.
However, the first step is to know where the Spirit Realm is.
The famous ancient "Crowned Wizard" Sigmund detailed this in his work, "Spirit Realm Origin", which is included in collections by various schools.
The Spirit Realm connects to the spiritual world of all intelligent life!
According to his theory, the spiritual world of humans is divided into three parts: consciousness, individual unconsciousness, and collective unconsciousness.
To use an analogy.
The inner world of humanity is like a vast archipelago, with the land above the water representing the awakened parts of some individuals' consciousness; the part of land revealed by tidal movements represents the individual's personal unconsciousness; and the sea bed serving as the foundation of all islands is the collective unconsciousness.
