O thou who art spreading the Cause of God! I hope thou wilt become as a rising light and obtain spiritual health—and spiritual health is conducive to physical health—so that thou mayest be enabled to liquidate thy debts and be strengthened to attain the blessing of the Forgiving Lord; that thou mayest become a mirror of truth and reveal the spiritual brilliancy of the heavenly universe to all eyes, direct large numbers of people under the shadow of the Powerful Lord and guide all thy family and relations unto the Greatest Guidance; and that thou mayest be honored with a visit to the Holy Threshold after having attained to all these gifts.
