A mathematical model of nature is useful in the study of this system. A comprehensive mathematical model of the loka must consider all the existential to arrive at a realistic result. A simplified model of the loka can be made based on the following considerations.
- Presence of matter, both gravitational (eight-touch) and non-gravitational (four-touch). A suitable ratio of the two types can be assumed.
- A uniform electric field due to the dynamic charge of paramanus (two-touch) extending through the whole loka.
- The body of a mobile jiva has a continuous input and output of matter of both the gravitational and the non-gravitational types. The mobile jiva, therefore, can be modeled as a pair of source and sink of such matter. A uniform distribution of source-sink pairs can be assumed all over the trasanadi. The subtle immobile beings in the outer loka are a different class and do not possess this property.
- Dharmastikaya and adharmastikaya as agents of motion and non-motion respectively. A linear variation along the trasanadi axis can be assumed.
- Presence of GMV matter in the middle loka only, which can be assumed to be flat.
- Presence of electrically charged spaces in the trasanadi, with a positive pole in the upper loka and a negative pole in the lower loka.
- Akasa, space for all other components realities
- Empirical time for measuring the duration of events.
- Boundary conditions. The outer layers are free of life and therefore do not have eight-touch kinds of matter. These layers contain four-touch matter that can provide a force against gravity. Further, this matter is supposed to have a negative charge. Thus, the overall effect of the outer layers is to retard the motion of matter and provide a force against any tendency toward expansion. So, the outer layers can be modeled as a uniform force acting inwards on the boundary. Defining boundary conditions in this way effectively presupposes a finite loka, but this is not objectionable since most cosmologists believe that the universe could not be infinite.
As a first approximation, a two-dimensional model can be made because the loka on axial planes is expected to be similar.
