My health and happiness are in this, when I see the friends of God engaged in spreading the divine fragrances, arising to serve the Cause of God, forgetting every thought save that of teaching, casting into the corner of forgetfulness every matter but that of unity and harmony. Consider in every age what confirmation and assistance were received by those souls who devoted their time to serving the Cause and spreading the divine fragrances. On the contrary, those who were absorbed by personal interests or political affairs degraded not only themselves but their associates. Thus, in this day, the friends of God should see that all glory lies in teaching the Cause of God and that every happiness is found in the shadow of the Word of God.
