A: Here is the question of concentration, and not of its effect. The question of effect is quite a different subject again. Then the question comes: of what object? Something to steady the mind. It may be a tree, a flower, the sun or a star. Of course, according to the object a reaction is produced. And according to the reaction an object is produced. Every belief and every experience for a wise person is a step of a staircase. He has taken this step, there is another step for him to take. The steps of the staircase are not made for one to stand there. They are just made for one to pass, to go further. Because life is progress. Where there is no progress there is no life. One should go on. Death and disappointment -- two things are one. And if there is a hereafter, then the death was a passing stage, and so is disappointment. Two things are one. And if there is a hereafter, then the death was a passing stage, and so is the disappointment. It only has made one more steady, more wise, more. . .
