I don't know what he says after but could this be it or similar?
Dedication of Merit
Yānaññāni katāni me
Tesañca bhāgino hontu
May all beings — without limit, without end —
have a share in the merit just now made,
and in whatever other merit I have made.
Ye piyā guṇavantā ca
Diṭṭhā me cāpyadiṭṭhā vā
Those who are dear & kind to me —
beginning with my mother & father —
whom I have seen or never seen;
and others, neutral or hostile;
Sattā tiṭṭhanti lokasmiṃ
beings established in the cosmos —
the three realms, the four modes of birth,
with five, one, or four aggregates —
wandering on from realm to realm:
Ñātaṃ ye pattidānam-me
Anumodantu te sayaṃ
Ye cimaṃ nappajānanti
Devā tesaṃ nivedayuṃ.
If they know of my dedication of merit,
may they themselves rejoice,
And if they do not know,
may the devas inform them.
Sabbe sattā sadā hontu
By reason of their rejoicing
in my gift of merit,
may all beings always live happily,
free from animosity.
Tesāsā sijjhataṃ subhā.
May they attain the Serene State,
and their radiant hopes be fulfilled.
This offering maybe right, or wrong, but it is one, the other, both, or neither!

"Others will misconstrue reality due to their personal perspectives, doggedly holding onto and not easily discarding them; We shall not misconstrue reality due to our own personal perspectives, nor doggedly holding onto them, but will discard them easily. This effacement shall be done."
