Wherefore must the friends of God, with utter sanctity, with
one accord, rise up in the spirit, in unity with one another, to such a degree
that they will become even as one being and one soul. On such a plane as this,
physical bodies play no part, rather doth the spirit take over and rule; and
when its power encompasseth all then is spiritual union achieved.
- ‘Abdu’l-Baha (‘Selections from the Writings of ‘Abdu’l-Baha’)
