Supreme is any Blessed One:

It was through understanding, that the Blessed
One rediscovered the True Dhamma!
It was through compassion, that he taught it
thoroughly to the multitude of beings.
It was through understanding, that he felt disillusion with this
round of rebirth .
It was through compassion, that he endured it
long, while learning to liberate
others.
It was through understanding, that he fully understood other
being's suffering.
It was through compassion, that he undertook to counteract their
immense misery.
It was through understanding, that he himself crossed over
the flood to Nibbāna!
It was through compassion, that he brought other beings across
this flood also...!
It was through compassion, that he practised
and taught no-cruelty towards others.
It was through understanding, that he himself was fearless of all other
beings.
It was through compassion, that he became this world's only really
ultimate helper.
It was through understanding, that he became his own
final and absolute helper.
It was through compassion, that he
for long was humble and gentle as a Bodhisatta.
It was through understanding, that he gained majestic dignity as a
worthy Buddha.
It was through compassion, that he helped all beings as a safeguarding
good father.
It was through understanding, that he remained detached from all being's
craving.
It was through understanding, that his
own mind was detached
from all phenomena.
For just as the Blessed One's compassion was without
biased sentimental fondness,
so was his supreme understanding free from the concepts of "I"
"Me" and "Mine"...

Comments:
Observing understanding joined with compassion in
one and same person is quite unusual.
Why so?
An individual with high intelligence and understanding may
veer toward arrogant cynicism.
An individual with great
empathy & compassion may veer
toward being naive and impulsive.
Only the Awakened Ones embody both
full understanding and
fine compassion seamlessly.
These two abilities then mutually counteract each
other's deficiency enabling the fine
compassion to be ultimately able to - by razor-sharp
intelligence - to guide all beings
towards Nibbāna, which is the highest, safe,
sure, and uniquely lasting Happiness..
