Bahá’í World Faith—Selected Writings of Bahá’u’lláh and ‘Abdu’l-Bahá (‘Abdu’l-Bahá’s Section Only)

Unless the Holy Spirit become intermediary, one cannot attain directly to the bounties of God. Do not overlook the obvious truths, for it is a self-evident fact that a child cannot be instructed without a teacher, and knowledge is a bounty from the bounties of God. The soil is not covered with grass and green without the rain of the cloud; therefore the cloud is the intermediary between the divine bounties and the soil. A body doth not develop and grow without the soul; therefore the soul is the medium of the spiritual life.
