Differences of Man and Manalings

Man's life is consists of 3 parts: body, mind, soul
Man's life is taken away by death
Death breaks the connection of body and soul
Without soul, the mind will not be able to channel mana and contain mana in the body
If a body contains mana without the control of soul, it will become an undead.
If a soul with a mind strong enough to control the mana flow, it will become one of the mana spirit when the body is dead.

Manalings' life has 3 parts: Mana Beast, Mana Spirit, Mana Core

Different from man, Manalings can still be alive when these parts are separated.
Mana Core is equivalent to mind.
Mana Spirit is equivalent to spirit.
Mana Beast is equivalent to body.

First, the Mana Spirit from the Mana World will describe its unique identity and writes into runes, the runes is the base of Mana Core. 

Using the rune, the Mana Core will conjure itself forming its basic shape, then the Mana Core will record the description to form the Mana Beast.

Using available materials, the Mana Core will conjure the body together while structuring the script, which the script can also be used to summon the Mana Beast into the material world.

The script will record itself into the Mana Core once the Mana Beast is born.

When Mana Core lost its connection to Mana Spirit (caused by Void or Corruption), the Mana Beast will turn wild or insane. A wild Mana Beast will need to consume additional energy source, such as food, blood, nutrient, or mana flow of others. However, the option of energy source will be based on the material of the body (Mana Beast) itself.

When Mana Beast lost its Mana Core, the body will die and vanish.

The Mana Spirit channels mana (from the Mana World) into the Mana Core, the Mana Core then identifies the mana source and instructions from the Mana Spirit.

Void long enough can cause permanent break as the reserved mana no longer sufficient to sustain the energy link between the Mana World and the material world.

Corruption is the interruption of the instructions from the Mana Spirit, but not the mana source.

A Mana Beast that turned wild can also be a type of corruption as the instruction from the Mana Spirit no longer valid, yet the body has the basic instinct to sustain itself and live.
