Boldness doesn't mean rude, obnoxious, loud, or disrespectful. Being bold is being firm, sure, confident, fearless, daring, strong, resilient, and not easily intimidated. It means you're willing to go where you've never been, willing to try what you've never tried, and willing to trust what you've never trusted. Boldness is quiet, not noisy.
The wise say that it is not an iron, wooden or fiber fetter which is a strong one, but the besotted hankering after trinkets, children and wives, that, say the wise, is the strong fetter. It drags one down, and loose as it feels, it is hard to break. Breaking this fetter, people renounce the world, free from longing and abandoning sensuality.
