O friend, the heart is the dwelling of eternal mysteries,
make it not the home of fleeting fancies; waste not the treasure of thy
precious life in employment with this swiftly passing world. Thou comest from
the world of holiness—bind not thine heart to the earth; thou art a dweller in
the court of nearness—choose not the homeland of the dust.
(Baha’u’llah, ‘The
Seven Valleys and the Four Valleys)
