Mind - subtle material field

The mind is a subtle material field
- in which information is stored
- and has four main functions: Thinking, Feeling, Wishing and Consciousness.

This informational field is not affected by leaving the gross material body.
This is proved by the phenomena of decorporation studied in renowned clinics,
in cases of Near Death Experiences, where patients report that they have left their bodies,
and tell what they have seen around them,
looking at their own body and other people from outside the gross material body.

They usually suffered a more or less prolonged cardiac arrest, in which they weare considered to be "unconscious", or better said, as having no perception.

For this reason, health personnel and doctors were very surprised at the beginning of the reporting of these incidents.

Transcendental knowledge also confirms that the mind is a material element that the soul takes with it when it changes the gross physical body, see The Living Being and the 8 Material Divisions. 
So, the mind is not spiritual; the soul is the only thing that is spiritual in this material world in which we find ourselves.

The mental field has nothing to do with the other fields known in physics.

In energetical medicine, one of the etheric layers is associated with conceptualizing, thinking, reasoning, and interpreting events; this energy level surrounds the emotional field, as evidenced by the connection between thoughts and feelings.

The field theories of consciousness discussed in this article are theories about the nature of consciousness, in which consciousness is conceived as identical with a field in the general sense in which the term "field" is used in physics.

When one has been involved with a belief for a long time, it becomes one's second nature and one becomes attached to it. And because consciousness is the place of attachment, it becomes part of consciousness.

When
- other information
- in an amount at least as great as the amount of information that led to one's belief
- over a relatively long period of time, if it comes from unrecognized sources, or
- over a relatively short period of time, if it comes from recognized sources
- disprove the information on which the belief was based
- that belief disappears sooner or later,

This is called a consciousness shift.
