What is an Other-Self? Are 2D Entities Other-Selves?

[Confused]

Dear Monica, first of all, please accept my thanks and congratulations for a spiritually profound and insightful post. The questions raised are not only brilliant in their own right, but provoke deep contemplation too. With respect to the questions --

1. What is the definition of other-self?
As GV said, it is probably just that the lowest common denominator is the ALL SELF, akin to a singular vista being viewed from multiple vantage points. The views and aspects may appear different to each individual viewing a mountain range from several platforms around; but the target of the view line for all is essentially one.

2. Why is it assumed that other-self pertains only to humans?[b]

I do not think that is the case, Monica. In 41.4, Ra states that

Metaphysically, the sun achieves a meaning to fourth through seventh density according to the growing abilities of entities in these densities to grasp the living creation and co-entity, or other-self, nature of this sun body. Thus by the sixth density the sun may be visited and inhabited by those dwelling in time/space and may even be partially created from moment to moment by the processes of sixth-density entities in their evolution.

The question raised here may sound funny if evolutionarily elevated self-conscious beings such as the Sun were to contemplate if other-self natures were to be prescribed only to other-self beings of equal evolutionary stature. It is of course well to remember that 3D is the first density of fully formed self-consciousness or individual awareness, which is a attribute that 2D entities of a very advanced level within the 2D octave develop in the course of the evolutionary journey, thus developing a critical spiritual mass before tipping over into 3D status.

3. When, if ever, are 2D animals considered other-selves?

To give a purely technical reply, it is when 2D beings become a mind/body/spirit complex, or in other words, when the spirit portion of the combined being complex appears in the conscious perceptual range or radar for the first time.

13.21 Questioner: Then how does the second density progress to the third?

Ra: I am Ra. The second density strives towards the third density which is the density of self-consciousness or self-awareness. The striving takes place through the higher second-density forms who are invested by third-density beings with an identity to the extent that they become self-aware mind/body complexes, thus becoming mind/body/spirit complexes and entering third density, the first density of consciousness of spirit.

It is the abiding energies of life in all that is the spirit or the SELF, in my opinion.
