As your prayer and meditation become deeper, they will defend you
from the perpetual assaults of the outer world. You will hear the
busy hum of that world as a distant exterior melody, and know
yourself to be in some way withdrawn from it. You have set a ring
of silence between you and it; and behold! within the silence you
are free.
Conversation was never begun at once, nor in a hurried manner. No one was quick with a question, no matter how important, and no one was pressed for an answer. A pause giving time for thought was the truly courteous way of beginning and conducting a conversation. Silence was meaningful with the Lakota, and their granting a space of silence to the speech-makers and their own moment of silence before talking was done in the practice of true politeness, listening, and regard for the rule, "thought comes before speech."
