|The crozier is a common error -- she was never abbess|
It is tough to see, given what's recorded of her life, why she got the nod. She was entrusted to a convent in Helfta, Germany at age five, raised there, lived and died there. She was a helluva student, by all accounts, until she had a vision from the Lord turning her from secular topics to the study of the Bible and writings of the early Church leaders. She read and wrote and prayed a lot, interspersing it all with visions and prophecies.
