You throw no low blows and rise above the rest

Question

You throw no low blows and rise above the rest.

What does it mean?

Answer 1

A dictionary helps:

low blow noun
Boxing
an unlawful blow that lands below an opponent’s waist:
the referee hadn’t seen the low blow and declined to call a timeout
a comment or tactic regarded as unfair or unkind:
his mockery of Elizabeth’s work seemed like a low blow

rise above verb
succeed in not being limited or constrained by (a restrictive environment or situation):
he struggled to rise above his humble background
be superior to:
I try to rise above prejudice

[ODO]

Low blow comes straight from boxing but has been applied metaphorically to any unfair or underhand act.

“You do not act unfairly and are better than everyone else, who does act like that.”
