O Son of Man! Write all that We have revealed unto thee with
the ink of light upon the tablet of thy spirit. Should this not be in thy
power, then make thine ink of the essence of thy heart. If this thou canst not
do, then write with that crimson ink that hath been shed in My path. Sweeter
indeed is this to Me than all else, that its light may endure for ever.
- Baha’u’llah (‘The Hidden Words of Baha’u’llah’)
