Although you seem to feel that your prayers have not so far been answered, and do no longer have any hope that your material conditions will ameliorate, the Guardian wishes you nevertheless not to allow such disappointments to undermine your faith in the power of prayer, but rather to continue entreating the Almighty to enable you to discover the great wisdom which may be hidden behind all these sufferings. For are not our sufferings often blessings in disguise, through which God wishes to test the sincerity and depth of our faith, and thereby make us firmer in His Cause?

...The true worshipper, while praying, should endeavour not so much to ask God to fulfil his wishes and desires, but rather to adjust these and make them conform to the Divine Will. Only through such an attitude can one derive that feeling of inner peace and contentment which the power of prayer alone can confer.
