Sometimes the soul is set on fire
with the love of God
with a force that moves unerringly, but invisibly,
so that even the body is, as it were,
swept along into the abyss of that unspeakable love.
We can experience the force of that holy grace
when we are most vigilant, or even,
as I have spoken on other occasions,
in the way that sleep starts to affect us.
But when you feel this movement,
know for certain –
and it is a point of utmost importance –
that it is the motion of the Holy Spirit of God within us.
