There are some beautiful thoughts and words in that prayer! I looked up the word Akatheist, and found a list of other lovely prayers to read, on Saint Jonah dot org. Thank you so much! God bless you!
Akatheist means “not sitting” and indeed when we chant the Akatheists, we stand.
Here’s a link to chanting of the Akatheist to the Holy Theotokos which we chant on Fridays in Great Lent:
