Help with making out some English lyrics

[darri]

I'm trying to transcribe the lyrics of the Kyokushinkai anthem and I'm asking for help in discerning some of the lyrics. I have everything except what's highlighted here.

Fighting art of Mas Oyama
Martial heart stood still in Chiba <-- Is it correct?

https://www.youtube.com/watch?v=iVePgx2QX2A&t=1m29s
Always giving, be aren't vain <-- Is it correct?
Skillful life is samurai <-- Is it correct?

Flashy look ???? forceful encounters <-- What's this?
Smashed up bricks prove body soundness
Faceless voices in the sky
??? Kyokushinkai <-- What's this?

Martial heart stood still in Chiba <-- Is it correct?

Yes.

Always giving, be aren't vain <-- Is it correct?

I doubt it but it does sound that way. If it is, it's not correct English. The closest I can come that makes sense is be not vain, but I'm not at all convinced.

Skillful life is samurai <-- Is it correct?

Yes.

Flashy low kicks, forceful counters
Smashed up bricks prove body soundness
Faceless voices in the sky
shouting Kyokushinkai

It sounded like be not vain to me.
