Joy is experienced by worldly attainment; peace is the attainment of heaven. In the ordinary sense we call it peace to be at rest in an armchair, on cushions, or in bed. But when the body is on a comfortable couch, does that mean that the mind is resting on cushions also? Cannot the mind go through torture at the same time? If that be the case, of what benefit is the peace and comfort of the body? The whole being must have peace. The mind must have peace from anxieties, worry, and from the greed that gives us ambitious desires and that we call "wrong" and "sin." When all this has gone, the mind is at rest. Then, when the heart is at peace and has done its work of love, the heart has enough; it ceases to be interested in any particular object in life, but is equal towards all. When there is no demand there is peace, and this peace helps towards peace of the soul.
