I set the date to pull the sword penetrating my spine. I had to do this alone. I wanted to avoid taking the risk of being interrupted halfway. In India, the vertebrae are called Sushumna, through which the energy flows. The points of seven chakras are placed inside that. According to the knowledge that I received, the one located at the bottom of the vertebrae is a chakra called Muladhara. In the sacrum, Svadisthana. In the solar plexus of the abdomen, Manipura. It might be easier to understand to call this dantian in Chinese. Above that, at the level of the heart, Anahata. Then, in the throat, Vishuddha. And, on the forehead, Ajna. At the crown of the head, Sahasrara. These seven chakras are said to correspond to seven endocrine glands and also to the parts or the functions of the body, respectively.

Muladhara at the bottom of the vertebrae relates to the adrenal gland.
And, it is said to correspond to the vertebrae and the kidney.
Svadisthana in the sacrum relates to the reproductive gland.
And, it is said to correspond to the reproductive organ.
Manipura in the the solar plexus relates to the pancreas.
And, it is said to correspond to the stomach, the liver, the gallbladder, and the nervous system.
Anahata in the heart relates to the thymus.
And, it is said to correspond to the heart, the blood, and the circulatory system.
Vishuddha in the throat relates to the thyroid.
And, it is said to correspond to the vocal cord, the trachea, and the digestive system.
Ajna at the front of the head relates to the pituitary gland.
And, it is said to correspond to the lower part of the brain, the left eye, the ear, the nose, and the nervous system.
Sahasrara on the head relates to the pineal gland.
It is said to correspond to the upper brain and the right eye.

It is the fundamental concept that each chakra has supernatural power, so if it is developed in the right way, it will be possible to have control over all kinds of psychic abilities, including second sight.
