What is inplied about the characteristics of the creator of the tiger

In
"" the speaker seems to question that such a creator could even exist, by
saying:

What immortal hand or eye

Could
frame thy fearful symmetry?

At the close the question is
rephrased slightly as:

Dare frame thy
fearful symmetry?

The speaker is trying to come to grips
with the fact that any being has created the tiger, and is trying to fathom
the nature of that being.

One has to ask what is so unfathomable or
spectacular about the tiger that the speaker is mystified by the nature or identity of its
creator.Blake uses the tiger as aof what we might equate with the Dark Side. This is what much
of his verse is about, not just here but in general. How or why, he seems to ask, would God (for
he's obviously talking about what most people, of any religion, or perhaps of no actual religion
at all, are conceptualizing as God) create the Dark Side? Perhaps the most significant stanza is
the penultimate one:

When the stars threw down their
spears

And watered heaven with their tears:

Did he smile
his work to see?

Did he who made the lamb make thee?

This implies several unexpected ideas that perhaps change the
direction of the poem. First, "the stars" are a kind of alternative creator. It is
they who "threw down their spears," symbolizing violence of some kind, but wept while
doing so, as if regretting the action of creation. Yet the speaker reverts to the singular
pronoun "he" as if returning to the more conventional belief in a single Creator, but
again questioning that the creator would approve of his own work, and also was capable of
creating such opposites: the lamb and tiger, good and "evil."

Blake's philosophy is one that merges these opposing forces and either tries to
reconcile the two, or states that both must be accepted as facts, as reality. Yet in "The
Tyger" he asserts, essentially, that the Creator is unknowable or inexplicable in having
made a cosmos in which such divergent elements can exist side by side. It is even possible that
in the repeated questioning about the nature of this life-giving force, Blake is making an
agnostic assertion: that he does not know if a Creator even exists.
