I am practicing in a weird world

In the classroom, the students were waiting for the teacher to start class. Suddenly, strange school rules were heard on the school radio.
1: Due to unknown reasons, the school is in danger and is closed for seven days. It will be reopened after seven days. Please prepare your daily necessities and do not attempt to leave the school during this period, otherwise we will not be able to protect your safety.
2: Darkness is dangerous, light is safe. For your own safety, please try to stay in the light.
3: Scissors and nail clippers are dangerous, please be sure not to bring them with you, otherwise you will be at your own risk.
……
After hearing this strange school rule, the students were stunned.
Seven days later...
The primordial spirit is an innate nature, like a baby who is unconscious but has feelings and agility. It is something that everyone possesses. After awakening, it can sense the power of ghosts, killing, the seven emotions and six desires, gaps, the mind, etc. These powers are called principles.
With the secret teachings as the foundation, let the principles spread throughout the body. As long as the foundation is not broken, the body will not die. Having two lives, the body and the foundation, is the basis for building the foundation and passing through the Pure White Gate.
