Nid wy’n gofyn bywyd moethus,
Aur y byd na’i berlau mân:
Gofyn wyf am galon hapus,
Calon onest, calon lân.

Cytgan
Calon lân yn llawn daioni,
Tecach yw na’r lili dlos:
Dim ond calon lân all ganu-
Canu’r dydd a chanu’r nos.

Pe dymunwn olud bydol,
Hedyn buan ganddo sydd;
Golud calon lân, rinweddol,
Yn dwyn bythol elw fydd.

Hwyr a bore fy nymuniad
Gwyd i’r nef ar edyn cân
Ar i Dduw, er mwyn fy Ngheidwad,
Roddi i mi galon lân.

“A Pure Heart”

I don’t ask for a luxurious life,
the world’s gold or its fine pearls:
I ask for a happy heart,
an honest heart, a pure heart.

Chorus
A pure heart is full of goodness,
More lovely than the pretty lily:
Only a pure heart can sing -
Sing day and night.

If I wished worldly wealth,
He has a swift seed;
The riches of a virtuous, pure heart,
Will be a perpetual profit.

Late and early, my wish
Rise to heavan on the wing of song,
To God, for the sake of my Saviour,
Give me a pure heart.
