PM Chapter 3: Substantiality of Self

Reference: Postulate Mechanics

Substantiality is an important aspect of Self. When something is substantial, it means that it exists and it can be sensed. Therefore, anything substantial is made of substance. 

If self is substantial, then it has to be made of substance.

Generally substance is identified as matter, but substance is more than just matter. Einstein famously showed radiative energy to be equivalent to matter with his equation, E = mc2. Experiments have shown further that the light from the sun can push a large sail in outer space. Thus, we may place radiation also in the category of substance.

When we think of a rose, and we get a picture of a rose. Obviously, this mental image picture exists and it is being sensed; and so it is substantial. A mental image picture has to be made of substance.

Since mind only senses thought, a mental image picture must be made of thought. Therefore, thought can also be viewed as a substance. This is not acknowledged by science; and we shall look at this shortcoming of science in a later chapter.

In Postulate Mechanics, we divide the substance of universe into three categories: 

  1. Matter
  2. Radiation
  3. Thought

Substance has consistency—a degree of density, firmness, viscosity, etc. When the substance is matter, we refer to its consistency as “mass.” Matter has a “spectrum” based on the mass of its atoms. This spectrum is presented as the Periodic Table. We are very familiar with matter. Our body is made of matter, whose mass we feel as weight. 

When the substance is radiation we refer to its consistency in terms of “frequency.” Radiation has an Electromagnetic Spectrum based on the frequency of its quanta. The consistency of radiation is high when its frequency is high. Our body generates heat, which is a form of radiation. Light is also a radiation, which forms our vision.

Thought as a substance has consistency of a very different type. We may refer to the consistency of thought in terms of the “gravity” of its consequences. Thought does affect the body and its functions, as well as the functions that body carries out. Thought can have a spectrum too based on the gravity of its consequences. The consistency of thought is high when its gravity is high. 

Matter and Radiation are considered to be physical substances. The spectrum of matter may be placed above the Electromagnetic Spectrum of radiation.

Thought, which includes postulates, is considered to be a spiritual substance. The spectrum of thought may be placed below the Electromagnetic Spectrum of radiation. The spectrum of thought is yet to be researched fully.

We may say that the Substantiality of Self covers the whole spectrum from thought to radiation to matter. This substantiality may also be expressed in terms of motion. Thought is said to move much faster than radiation. Radiation is known to move must faster than matter.

Notes and Postulates

The major concepts introduced in Chapter 3 are SUBSTANCE, MATTER, RADIATION, THOUGHT, CONSISTENCY and MOTION. These concepts are defined in Glossary: Postulate Mechanics.

PM Postulate 3.1: The postulate of the substantiality of self appears as substance.
PM Postulate 3.2: The substance has a spectrum from thought to matter.
PM Postulate 3.3: Matter is most concentrated and thought is the least.
PM Postulate 3.4: Matter has the least motion and thought has the most.
PM Postulate 3.5: Matter and radiation are physical; thought is spiritual.

    Very interesting. I’d never thought of light as substance or a type of ‘matter’.
    BTW although I don’t comment often, I want you to know that I read every post. I very much appreciate what you do.
