It Seems a Paradox
That at this moment of maximum frailty, of maximum existential dread even, she would ask for the power to bless all creatures great and small, all men and women great and small in particular.
But she is an instrument of the blessing, not the ultimate hand behind it. She is blessed with the power to bless. It is one of the ways in which the humble are exalted. (Father Zosima in Karamazov of course comes to mind.)
Some have argued that the Beatitudes of the Sermon on the Mount are mistakenly translated. It is not "Blessed are the meek" but rather "Beloved are the meek." Perhaps, in the foundational text, one word captures both meanings, or there is a single meaning that we followers have artificially cloven. "It comes to the same thing" I want to say.
