A home schooling friend sent me this prayer, cited at the Aquinas College website as one of Thomas Aquinas's prayers. It's a good one for those beginning their studies in a new school year or on a new school day. It's also a good one for those whose work is study.
Here is part of the prayer:
You are proclaimed
the true font of light and wisdom,
and the primal origin
raised high and beyond all things
Put forth a ray of your brightness
into the darkened places of my mind;
disperse from my soul
the twofold darkness
into which I was born;
sin and ignorance
You make eloquent the tongues of infants.
refine my speech
and pour forth upon my lips
the goodness of your blessing.
Grant to me
keenness of mind,
capacity to remember,
skill in learning
subtlety to interpret,
and eloquence in speech.
guide the beginning of my work,
direct its progress,
and bring it to completion.
You who are true God and true man,
who live and reign, world without end.
