Every man can cry for a vision, or "lament"; and in the old days we all -- men and women -- "lamented" all the time. What is received through the "lamenting" is determined in part by the character of the person who does this, for it is only those people who are very qualified who receive the great visions, which are interpreted by our holy man, and which give strength and health to our nation.
