@oristarA,
"But it would be equal to saying "only my illusion is true, and yours, NO!" It sounds domineering, not convincing. " ~ OristraA
That is a false claim.
{and also, I am wondering how you got red text... I don't seem to have that option. I searched.}
"Alone among illusions is my Illusory Body true" -
ALONE, does not mean ONLY.
Alone indicated that the Body is "lonely".
As if to say, there is no compassionate, sympathetic/understanding, comforting companionship.
Only voices and faces surround the author and they have no friends.
"Among Illusions " indicates that the lonely character is SURROUNDED by things it cannot connect with. As if to say, they cannot be real if they can be so distant and inconsiderate.
"IS my Body" / "My Body Is" : means that the body exists in the previously established situation.
"True." In the condition of a poetic metaphor is not comparative to a Scientific Fact, or the true nature of Truth.
By writing a cynicle poem... - THIS IS a cynical poem -
The definition of Truth has been obscured by "Depression".
Thus; He is not saying nothing else is true,
the author is saying,
"Alone among the illusionary existence of these heedless, aimlessly wondering, ignorant people who do not know me, of all the things that I perceive and understand, only what I think and see is truly founded on facts [Others ramble on about nonsense.]",
and furthermore,
"And LEST a person demonstrate logic, then I am right."
as that notion naturally exists whether written or not, as the number 0 is before every other number 01.00 / 045.000, 00 / 099999.9900
