A holy and disciplined mind turns
from ignorance and falsehood,
ignoring their myriad distractions,
while the soul stands firm, allowing
Wisdom to have her way.
~ from WALKING WITH WISDOM by Nan Merrill
If the heart wanders or is distracted, bring it back to the point quite gently -- and even if you do nothing during the whole of your prayer but bring your heart back, though it went away every time you brought it back, your time would be very well employed.
