Yasadattattheragāthā  Yasadatta

“Upārambhacitto dummedho,  With fault-finding mind, the simpleton
suṇāti jinasāsanaṁ;  listens to the victor’s instruction.
Ārakā hoti saddhammā,  They’re as far from the true teaching
nabhaso pathavī yathā.  as the earth is from the sky.

Upārambhacitto dummedho,  With fault-finding mind, the simpleton
suṇāti jinasāsanaṁ;  listens to the victor’s instruction.
Parihāyati saddhammā,  They fall away from the true teaching,
kāḷapakkheva candimā.  like the moon in the waning fortnight.

Upārambhacitto dummedho,  With fault-finding mind, the simpleton
suṇāti jinasāsanaṁ;  listens to the victor’s instruction.
Parisussati saddhamme,  They wither away in the true teaching,
maccho appodake yathā.  like a fish in a little puddle.

Upārambhacitto dummedho,  With fault-finding mind, the simpleton
suṇāti jinasāsanaṁ;  listens to the victor’s instruction.
Na virūhati saddhamme,  They don’t thrive in the true teaching,
khette bījaṁva pūtikaṁ.  like a rotten seed in a field.

Yo ca tuṭṭhena cittena,  But one with contented mind
suṇāti jinasāsanaṁ;  who listens to the victor’s instruction—
Khepetvā āsave sabbe,  having wiped out all defilements;
sacchikatvā akuppataṁ;  having witnessed the unshakable;
Pappuyya paramaṁ santiṁ,  having arrived at ultimate peace—
parinibbātināsavo”ti.  the undefiled are fully extinguished.”
