And what about the presence of natural, uncontaminated, landscapes?

那么自然的、未受污的景观的存在呢？

It's attention that comes from a pure mind — a mind uncontaminated by fear.

意力来自清净心——一颗没有被恐惧污的心灵。

Uncontaminated runway width is about 30 meters.

未受污的跑道宽30米。

That is why the few who do not, or who are believed to have remained uncontaminated, have so great and passionate a burden of admiration and longing laid upon them.

这就是什么少数没有被污的人，或者被认没有受到污的人，有如此巨大和热情的钦佩和渴望的负担放在他们身上。
