The following verse is taken from the Guru Granth Sahib, the sacred book of the Sikhs. For more about Guru Nanak, the founder of the Sikh religion, see this post.

Discipline is the workshop;
     patience, the goldsmith;
          the anvil, one’s thinking;
               wisdom, the hammer;
Fear, the bellows;
     austerities, the fire;
          and feeling, the vessel
               where the deathless liquid is poured.
In such a true mint
     is forged the Word,
          and those on whom He looks
               do their rightful deeds.
Nanak says:
     the One who sees,
          sees.
               He observes.
