Come, Holy Spirit

Come, O true light!
Come, O eternal life!
Come, O hidden mystery!
Come, O indescribable treasure!
Come, O ineffable thing!
Come, O inconceivable person!
Come, O endless delight!
Come, O unsetting light!
Come, O true and fervent expectation
of all those who will be saved!
Come, O rising of those who lie down!
Come, O resurrection of the dead!
Come, O powerful one,
who always creates and re-creates and transforms
by your will alone!

...
Come, you whom my wretched soul
has desired and does desire!
Come, you who alone go to the lonely
for as you see I am lonely!
Come, you who have separated me from everything
and made me solitary in this world!
Come, you who have become yourself desire in me,
who have made me desire you,
the absolutely inaccessible one!
Come, O my breath and life!
Come, O consolation of my humble soul!
Come, O my joy, my glory, and my endless delight!

I thank you that you have become one spirit with me,
without confusion, without mutation,
without transformation, you the God of all;
and that you have become everything for me,
inexpressible and perfectly gratuitous nourishment,
which ever flows to the lips of my soul
and gushes out into the fountain of my heart,
dazzling garment which burns the demons,
purification which bathes me
with these imperishable and holy tears,
that your presence brings to those whom you visit....
