the heart is the dwelling of eternal mysteries,...

"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,"
