Beyond the space we inhabit, there exist nearly a hundred dimensional spaces. Taoist practitioners study how the human soul can freely enter and exit these spaces. For easier understanding, they divide these spaces into three distinct parts. The lower part is filled with the darkest and most evil souls, life forms, and the cruelest, most horrifying scenes. The middle part is filled with purity and tranquility. The highest part of space is where the immortals reside. The goal of those who practice Taoism is to allow their souls to travel through various spaces and understand the operating laws of the multiverse through cultivation and improvement of personal abilities.
If one can cultivate to the point where the soul freely explores various spaces, it can be said that they have entered the stage of "attainment of the Dao." The body will possess abilities that ordinary people do not have. According to the Taoist classic "The Daoist Canon of the Transmission of Dharma Succession," those who attain the Dao cultivate extraordinary abilities in their body, eyes, ears, nose, tongue, and mind.
