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

[godwide_void]

The core of the perception of what is the distinction between self and other-self begins with the examination of the context of the 'self' being used and what it is encompassing. It does not refer to the self you know to be your decorative personality and form which you have gotten accustomed to identifying as being your actual identity due to the duration of your incarnational experience. The self being referred to is the indwelling observant essence which is the One Infinite Creator. An other-self is not referring to the notion that everyone you see around you is a clone of your physical 'you' manifestation in any way except when considering the attraction of circumstances and beings of similar vibrational orientation or any particular distortions you hold. It simply means that it is another form which the One Infinite Creator has taken. Animals are a form which the Creator has taken. Plant life too are lower manifestations of Its being. The elements as well are portions of its awareness which have undergone fragmentation. There exists only one singular being which is the Self of all selves for all selves exist as cells within the body of this all-encompassing Self. Service to other-selves thus denotes that one aspect of the Creator, being entirely the Creator, is positively interacting with another portion of the Creator, being entirely the Creator. In any mass interaction which takes place there exists only one being doing the interactions even if the lower manifestations are not aware of that which takes the reigns of their being and believe themselves to be creatures of separation and privacy. It is impossible for any self to be a distinct self outside of the influence of the One Infinite Creator. No individual is ever alone in any moment for one's awareness is not a confined island at the complete command of the visible manifestation of what one may constitute their 'self'. I will thus leave you with a quote which I have recently taken a liking to for its profundity and relevance to this excellent discussion topic of yours:

O Sariputra,
Form does not differ from the Void,
And the Void does not differ from Form.
Form is Void and Void is Form.
The same is true for feelings, perceptions,
volition, and consciousness.
