We are much more than what we can see and touch.
The constitution of the human being goes beyond the physical body, and what we really are was not ignored by the ancient and wise forms of Egyptian, Chinese, Indian medicine, among others.

We will talk in this first lesson about the bodies or vehicles that are part of the human being constitution and about its psychological aspects as well.

The following graphic shows us a representation of the human being constitution:

Physical Body is the vehicle with which we express ourselves in this physical, three-dimensional world. This body is subject to time; it deteriorates as time passes until someday its biological functions ceases.
It is the physical death of this vehicle.

Vital Body is a section of the physical body correspondent to the fourth dimension, or in other words, it is a body closely linked to the physical body that does not belongs to our well-known three-dimensional world; it belongs to the fourth dimension.
The vital body is also known as aura or etheric body. It is this body that gives vitality to the physical body.
When the vital body starts to deteriorate because it is also subject to time, the physical body follows to the same way. When the death of the physical body occurs, the vital body also disintegrates.

Astral Body is the vehicle with which we express ourselves in the astral world or the world of the dreams.
This vehicle is not subject to time, doesn’t die or disintegrates when the physical death occurs.
This body is linked to the physical body by the so-called silver cord; also know by cord of the life. It is an energy thread that only breaks at the moment of the physical death.
With the astral body we can act consciously out of the physical body and visit several places in the astral world. It is what is known as astral journey, astral projection, lucid dreaming etc. This issue will be addressed in detail in this course.

Mental Body is the vehicle with which we express ourselves in the mental world and, as the astral body, it doesn’t die nor disintegrate when the physical death occurs. The mental body is related to our thoughts and mental functionalisms.

We have mentioned above the vehicles or bodies we have. Let’s see what control these vehicles, what we are inside.

Essence, conscience, or soul is what the most noble we have. In the East Essence is also known as Budhata.
It is what we really are, but unfortunately it is so asleep and imprisoned in our so many psychological defects (which we also call “selves”) that rarely can express itself.
The Essence is immortal.
In a newborn, the Essence express itself free from the psychological defects, what makes these children beautiful, innocents and lovely.
Unfortunately, the Essence turns back to be imprisoned in the “selves” over time, and that spontaneous beauty starts to fade.

Ego is the set of all psychological defects we have, also called “selves” or “self details”. In spite of its inhuman nature, it is also what we are.
As the imprisoned Essence rarely expresses itself, what is on the control of our bodies and our actions is the Ego at most of the time. And that is really bad as we will see along the course.
As the previous graphic shows, we have:

  • 3% of free Essence (nevertheless asleep)
  • 97% of an Essence imprisoned in the Ego.

The selves are like different people living inside us, each one with its own interests, opinions, desires, thoughts etc. Each one of these “people” constantly fights for superiority, to become the commander of the human machine.

There is nothing superior or divine in the ego. Without any doubt the ego is the cause of our sufferings, unconsciousness, and limitations.
The ego doesn’t die when the physical death occurs. Happily, as we will see, it can be eliminated from us, by ourselves, in a conscious and voluntary way.
