The science of numbers is one of the common sciences, but the aim of 'Abdu'l-Bahá is, that the Heavenly Knowledge and Divine Wisdom encircle the world of existence. Shouldst thou desire to become my pupil thou must acquire the Mysteries of God and attain to the Knowledges and Sciences of the Kingdom-for they are the cause of the life of the world and the salvation of humanity. Upon thee be greeting and praise!
- ‘Abdu'l-Baha (From a Tablet; Star of the West, vol. 1, no. 6, June 24, 1910)
