During thy supplications to God and thy reciting, “Thy Name
is my healing," consider how thine heart is cheered, thy soul delighted by
the spirit of the love of God, and thy mind attracted to the Kingdom of God! By
these attractions one's ability and capacity increase. When the vessel is
enlarged the water increases, and when the thirst grows the bounty of the cloud
becomes agreeable to the taste of man. This is the mystery of supplication and
the wisdom of stating one's wants. (‘Abdu’l-Baha, quoted by J.E. Esslemont in "Bahá'u'lláh
and the New Era"; The Compilation of Compilations vol. II, The Importance
of Prayer, Meditation and the Devotional Attitude)
