help with small line of Fate/stay night


This is a small part of Rin's summoning chant in Fate/stay night:

> 四方{しほう}の門{もん}は閉{と}じ、王冠{おうかん}より出{い}で、王国{おうこく}に至{いた}る三叉路{さんさろ}は循環{じゅんかん}せよ。

I have some questions about this...

The last part mean: rotate the three-forked road (order)...? I say it because
I don't know what the function of は here... It used to add emphasis? It is
replacing other particle?

With what naruto said, it could be translated as:

> Close the four cardinal gates, leave the crown, and circulate through the
> three paths that reaches the kingdom.




循環する is [an intransitive verb which can take
を](https://japanese.stackexchange.com/q/3243/5010) (e.g., 血液が体を循環する "Blood
circulates through the body"). I think this は is replacing を, topicalizing the
三叉路. It effectively means 三叉路を循環せよ.

It says something (one who is summoned?) must start from the crown, circulate
through the 三叉路, and finally reach the kingdom.

Some people seem to believe this line refers to the [Tree of
Life](https://en.wikipedia.org/wiki/Tree_of_life_\(Kabbalah\)), which
describes the process of creation, starting from The Crown and ending with The
Kingdom. 三叉路 seems to refer to the three "columns/pillars" in the Tree of
Life, through which the creation circulates [in this
order](https://en.wikipedia.org/wiki/Sephirot#Listings).
