In Buddhist doctrine, there is a concept of the "middle yin body", which is of course a product of the development and improvement of Buddhist doctrine by disciples after the extinction of the Buddha. Because Shakyamuni Buddha was different from Hinduism when he founded Buddhism, although they both talked about reincarnation, Buddhism believed that there was no entity of "reincarnation". In Hinduism and even Taoism in China, it is believed that reincarnation is tangible. Taoism believes that the entity of reincarnation is the earth soul in the "three souls". When a person dies, the seven souls disperse, and the three souls return to their respective places. The heaven soul returns to the heavenly prison, and the earth soul returns to the underworld. After entering reincarnation, the human soul wanders between heaven and earth. After the reincarnation of the Earth Soul, the three souls will reunite.
Because Buddhism says that reincarnation does not have a physical entity, what exactly is reincarnation? Buddha says it is karma, and due to the pull of karma, the combination of causes and conditions gives birth to the cycle of sentient beings.

Taoism believes that the human soul wanders between heaven and earth, therefore, before the earth soul is reincarnated, the human soul, also known as the soul, will wander around. According to the teachings of Shakyamuni Buddha, humans do not have a physical entity of reincarnation. However, hundreds of years after the Buddha's death, some Buddhist disciples of certain sects believe that sentient beings exist as "intermediate beings" before their bodies are lost and reincarnated again, also known as "intermediate yin bodies".

Therefore, we know that the middle yin body refers to the existence form of sentient beings between the moment of death and the moment of life.

From this, we know that there is a difference between the Yin body and ghosts, and their difference lies in:

1. Different properties

The 'Zhongyin body' is a state of existence for sentient beings, while the 'ghost' is a karmic retribution. Buddha said that all sentient beings have three bodies: Dharma body, incarnation, and retribution body. All sentient beings have Dharma body, and only with divine power can they have incarnation. If there is karma, there is retribution body. When karma is fully repaid, the three bodies become one.

Ghosts, also known as' hungry ghosts', have a middle yin body, but the middle yin body is not a 'hungry ghost'.

2. Suffering is different

The 'middle yin body' does not suffer, or suffers very lightly. Buddhism believes that suffering is the act of karmic retribution. When reincarnation occurs in the six realms, karmic retribution leads to suffering. Hungry ghosts will suffer greatly when they report themselves, and no matter how much they eat, they always feel very hungry. Just suffering from hunger torment.

3. Different supernatural powers

When the "Zhongyin Body" exists, its divine power is at ease, and it can freely reach its desired place. It can walk through walls and traverse mountains, rivers, and the earth without being obstructed. Extremely active, its movement direction depends on past karma and habits.

However, the supernatural powers of the ghost body are limited, and they cannot escape from the ghost path, nor can they protect themselves from hunger.

4. Different durations of existence

The ghost body is a manifestation, with a duration that can be short or long, ranging from a moment to trillions of years. But the duration of the middle yin body is relatively short, with a maximum of no more than 49 days.
