The omikuji i gotten have a phrase i couldnt understand
高圓の 野辺の容花 面影に 見えつつ妹わは 忘れかねつも

This is a poem (tanka/short poem) written by Ootomo no Yakamochi, no. 1630 of Man’yooshuu まんようしゅう　万葉集).
https://en.wikipedia.org/wiki/Man%27yōshū;

It is an envoi to the preceding poem (chooka/long poem), no. 1629.

And you pronounce it in modern Japanese as follows:
たかまとの Of Mt. Takamato
のべの In the fields
かおばな A convolvulus
おもかげに On its face
みえつつ I cannot stop seeing you
いもは My sweetheart
わすれかねつも I cannot forget you.

So, we have a literal translation (not very poetic) as:
In the fields of Mt. Takamato (where I stroll to forget you, my sweetheart!), a convolvulus face inevitably reminds me of you, sweetheart!

Did you visit Nara? Mt. Takamato is one of the surrounding hills of Nara city.
