From the theory of traditional Chinese medicine, the so-called need to replenish yang does not mean how your own yin energy is, but that your own physical constitution is biased toward yin excess and yang deficiency, which means that the body's yang energy is insufficient, so Uneasy. The mind is dominated by the mind, which refers to conscious thinking, etc. Being sensitive to negative things means that the mind is unstable and prone to various associations and auditory and visual hallucinations.
Generally speaking, Yang deficiency is often accompanied by Qi deficiency. Everyone is born with their own righteousness, but it is blinded, covered, and weakened due to various circumstances. Therefore, everyone can re-certify and cultivate his own righteousness through various means. From the perspective of traditional Chinese medicine, it is also possible to nourish the innate after tomorrow.
So it’s not necessarily about seeing gods, seeing ghosts, etc.
