O Ysbryd Sancteiddiolaf

O! Ysbryd Sancteiddiolaf,
  Anadla arna'i lawr,
O'r cariad anchwiliadwy
  Sy'n nghalon Iesu mawr;
Trwy haeddiant Oen Calfaria,
  Ac yn ei glwyfau rhad,
'Rwy'n dysgwyl pob rhyw ronyn
  O burdeb gan fy Nhad.

Digoner fi a'th ddelw
  Ddigymhar uwch y nen,
A gollais yn Mharadwys
  Wrth fwyta frwyth y pren;
Rhoi'st imi fil fendithion,
  Ond byth anfoddlon wy',
O eisieu cael dy Ysbryd
  A'i anian nefol fwy.

Wel dyma'r man dysgwyliaf
  O fore hyd brydnawn,
Ar fy eilunod taeog
  Fod yn goncwerwr llawn:
Dy Yspryd, Iesu grasol,
  A all fy ngwneyd yn lān;
Mil mwy sydd ganddo o allu
  Nag sydd yn uffern dān.

'Mhen gronyn byddai'n gorwedd
  O fewn y ddaear ddu;
Y tafod sy'n gweddio
  Yr awrhon arnat Ti,
A bydra yn y dyfnder,
  Ni lefa arnat mwy;
O, edrych ar fy nghystudd,
  Iachā fy ngwahan-glwy'.

O! Ysbryd pur nefolaidd,
  Cyn 'r'elwy' lawr i'r bedd,
Trwy ryw athrawiaeth hyfryd,
  Gad imi brofi'th hedd!
Cael profi
    blas maddeuant,
  Maddeuant llawn a rhad,
Yw'r cynta' peth wy'n geisio,
  Yn awr trwy rin y gwaed.

O! Ysbryd Sancteiddiolaf,
  Anadla arna'i lawr,
O'r cariad anchwiliadwy

Trwy haeddiant Oen Calfaria,

Tyrd, Ysbryd Glān sancteiddiol,
  Anadla'r nefol ddawn:
Gwna heddiw gynnwrf grasol
  Mewn esgyrn sychion iawn:
Dy nerthoedd rhoi gydfyned
  Ā geiriau pur y nef;
Dy air yn nerthol rheded,
  Mewn goruchafiaeth gref.

O most Holy Spirit,
  Breathe down upon me,
From the unsearchable love
  Which is in the heart of great Jesus;
Through the merit of the Lamb of Calvary,
  And in his gracious wounds,
I am waiting every moment
  For purity from my Father.

Satisfy me with thy image
  Incomparable above the sky,
Which I lost in Paradise
  By eating the fruit of the tree;
Thou gavest to me a thousand blessings,
  But forever unsatisfied I am,
From need of getting thy Spirit
  And his heavenly nature evermore.

See here is the place I am expecting
  From morning until evening,
Over my servile idols
  To be a full conqueror:
'Tis thy Spirit, gracious Jesus,
  That can make me clean;
He has a thousand times more power
  Than there is in hell fire.

After a while I would be lying
  Within the black earth;
The tongue which is praying
  This hour to Thee,
Shall decay in the depth,
  It shall no more cry to thee;
O, look upon my affliction,
  Heal my leprosy.

O pure, heavenly Spirit,
  Before I go down to the grave,
Through some delightful teaching,
  Let me experience thy peace!
To get to experience
    a taste of forgiveness,
  Forgiveness full and free,
Is the first thing I am seeking,
  Now through the virtue of the blood.

O Most Holy Spirit,
  Breathe down upon me,
From the unsearchable love
  Which is in the heart of great Jesus;
Through the merit of the Lamb of Calvary,
  And in his gracious wounds,
I am waiting every moment
  For purity by my Father.

Come, sanctifying Holy Spirit,
  Breathe the heavenly gift:
Make today a gracious stirring
  Within very dry bones:
Thy powers grant to confirm
  The pure words of heaven;
May thy word run powerfully,
  In a strong supremacy.
