A couple linguistic questions about the Iroha poem


Here is the text of the Iroha poem, sided with a possible translation (mine):

色は匂えど Iro wa nioedo | Colors, although bright,  
散りぬるを Chirinuru wo | Will scatter.  
我が世誰ぞ Wa ga yo tare zo | In my world, nobody  
常ならぬ Tsune naranu | Is eternal.  
有為の奥山 Ui no okuyama | The remote mountains of the vicissitudes of life  
今日超えて Kyou koete | [I'm] crossing today,  
浅き夢見じ Asaki yume miji | Not dreaming shallow dreams,  
酔いもせず Ei mo sezu | [And] not getting/being drunk.

My questions are:

  1. What does the particle "zo" in l. 3 mean? Should I understand ll. 3-4 as 私（たち）の世には誰も常ならない "In my/our world, no-one is unchanging"?
  2. What verb form is "miji"?
  3. How would you suggest to translate the last line? "Not getting drunk"?

Any comments on my translation are naturally welcome.

[Note to self: "nioedo" ~ "niou keredo", it's an archaic verb form equating to
having a contrastive conjunction after (I believe) a present (or rather non-
past) tense.]




  * [ぞ](https://www.hello-school.net/haroajapa010030.htm) is an emphasis marker. 誰ぞ常ならむ is 誰が常であろう in modern Japanese. It is essentially a rhetorical question ("Who is eternal?"), but "Nobody is eternal" is a valid translation, too.
  * The last two lines have several possible interpretations, but assuming じ is voiced, it is a [negative volitional auxiliary (~I will not)](https://www.hello-school.net/haroajapa009021.htm). 酔いもせず connects to 浅き夢見じ. A literal translation would be "I will not have a shallow dream, nor will I get drunk/deluded".
