All realities and spirits are immortal, even the spirits of
non-believers and imperfect persons. But they cannot be compared in any way
with the spirits of the sanctified souls and holy personages. Although this
wood has existence, yet in comparison with the existence of man, it is as
nothing. (‘Abdu’l-Baha, from an address, August 8, 1912, Dublin, USA; ‘Mahmud’s
Diary’)
