No other Art — would do —
My Tactics missed a rudiment —
Creator — Was it you?
God grows above — so those who pray
Horizons — must ascend —
And so I stepped upon the North
To see this Curious Friend —
His House was not — no sign had He —
By Chimney — nor by Door
Could I infer his Residence —
Vast Prairies of Air
Unbroken by a Settler —
Were all that I could see —
Infinitude — Had'st Thou no Face
That I might look on Thee?
The Silence condescended —
Creation stopped — for Me —
But awed beyond my errand —
I worshipped — did not "pray" —

In astronomy, a subject Dickinson studied and enjoyed throughout her life, the term "period" refers to the length of time it takes an object to complete one revolution of its orbit or one complete rotation on its axis. In this poem, Dickinson has reached a point in her life's orbit where she felt the need to pray – nothing else "would do". And so she ventures out in astronomical space, for "those who pray / … – must ascend" to the realms above where "God grows". By "north" Dickinson is probably hearkening back to the Bible. In the book of Job (37:22), she would have read "Out of the north he comes in golden splendor; God comes in awesome majesty."
The poem begins with a lighthearted tone despite the speaker's urgent need to pray. Clearly frustrated in her attempt, she blames her "Tactics" for missing a "rudiment" of prayer. She then drolly asks God, her "Curious Friend", if this "rudiment" might be him. That's a bit cheeky!
The speaker consequently embarks on her search for God, and the next three stanzas offer some details of her journey – still in the bantering tone. "His House was not – no sign had He" is a sing-songy bit of chiasmus, and the sketch of the poet going about the heavens looking for a door or chimney is humorous.
Throughout her search, all the poet sees are "Vast Prairies of Air". She finally addresses God as "Infinitude" – a deepening of respect and awe. While looking for a friendly face, perhaps the grandfatherly god of much Christian art, she finds infinity instead.
The last stanza pivots to epiphany. The silence of unbroken infinity is suddenly open to her; "Creation" stops "– for Me–" she adds in amazement. The realization that she herself is axis, is at the heart of Creation, fills her with such awe that prayer and petition were forgotten in the exaltation of worship.
It is a larger sense of the divine, I think, that to reverence a Deity who listens to prayers as if a parent.
The poem is written in common ballad form except the last stanza which is all in iambic trimeter. That stanza is given additional emphasis by the alliteration of "condescended" and "Creation". The "stopped" followed by a dash really does stop the poem. It's the key moment as the poet finally gives up tactics for Silence and Infinitude.
