I'm sorry but I don't think this is a senryu. A Senryu/haiku shows rather than tells. Though, I've been thinking that perhaps you meant something different with the title as I have noticed that you often use parenthesis around the form. For instance ( senryu ) and this one doesn't. I also have no clue what Neti means... if you don't mind, could you give me a hint?
Neti is a Hindu concept also sometimes ascribed to Gautama when he was asked about what carries on after life. When asked if it was personality, or intentions, or dharma, or soul and so forth, his response was always "neti, neti" ("not this, nor that"). It is used to probe into the non-dualistic nature of existence.
Agnostic is neither a believer nor a non-believer.
This work has the form of a senryu, but it is "not this."
