Tyrd Ysbryd Glān, tragwyddol Dduw,
  Yr unrhyw ā'r Tad nefol;
Yr unrhyw hefyd ā'r Mab rhad,
  Duw cariad tangnefeddol.

Llewyrcha i'n clonnau ni ā'th ras,
  Fel byddo gās in' bechu;
Ac ini, mewn sancteiddrwydd rhydd,
  Bob dydd dy wasanaethu.

Tydi addawaist ddysgu, ION,
  Dy weision i lefaru;
Fel y'mhob man y caffo'n rhwydd,
  Yr Arglwydd ei foliannu.

O Ysbryd Glān i'n clonnau ni,
  Y gwir oleuni danfon;
A hefyd sźl, tra fōm ni byw,
  I garu Duw yn ffyddlon.

Dod fesur mawr o'th ras yn rhwydd,
  O Arglwydd Dduw goruchaf;
Dyddanwch i ni felly bydd,
  Yn y brawd-ddydd diweddaf.

  Galw 'rwyf arnat am dy fod
  O Yspryd Duw y Crewr mawr
  Tyrd Ysbryd Glān i'n c'lonau ni

Come, Holy Spirit, eternal God,
  The same as the heavenly Father;
The same also as the gracious Son,
  God of eternal love.

Shine into our hearts with thy grace,
  That our sins become hated;
And that we, in free sanctification,
  Every day serve thee.

Thou didst promise to teach, Lord,
  Thy servants to speak;
As in a place where freely,
  The Lord may be praised.

[O Holy Spirit into our hearts,
  Send the true light;
And also zeal, that we may live,
  To love God faithfully.

May a large measure of thy grace come freely,
  O Lord God most high;
A comfort to us thus it will be,
  On the last judgment-day.]

Come, Holy Ghost, our hearts inspire,
And kindle with celestial fire;
  Thou the anointing Spirit art,
  Who dost thy sevenfold gifts impart.

Thy blessed unction from above
In comfort, life, and fire of love;
  Enable with perpetual light
  The dullness of our blinded sight.

Anoint and cheer our soiled face
With the abundance of thy grace;
  Keep far our foes; give peace at home;
  Where thou art guide, no ill can come.

Teach us to know the Father, Son,
And thee, of both, to be but one;
  That through the ages all along
  Thy praise may be our endless song:

  Praise to thy eternal merit,
  Father, Son, and Holy Spirit.
