The advent of the prophets and the revelation of the Holy
Books is intended to create love between souls and friendship between the
inhabitants of the earth. Real love is impossible unless one turns his face
towards God and be attracted to His Beauty. The maid-servants of the Merciful
should love each other with heart and soul; for though there be many bodies,
the spirit of faith is one and the outpouring of the Holy Spirit is universal.
There is one Light but many lamps; there is one Wine but the glasses differ. So
thou shouldst love with all thy heart and soul the maid-servants of the
Merciful and associate with them in utmost affection in order that thou mayest
realize divine happiness and behold the outpouring of mercy.
(‘Abdu'l-Baha,
Tablets of ‘Abdu'l-Baha vol.3)
