“…attach your hearts to the ends and results”

Do ye not look upon the beginning of the affairs; attach your hearts to the ends and results. The present period is like unto the sowing time. Undoubtedly it is impregnated with perils and difficulties, but in the future many a harvest shall be gathered and benefits and results will become apparent. When one considers the issue and the end, inexhaustible joy and happiness will dawn.

Live thou as far as thou art able according to the divine commands and advices, because they are conducive to eternal life. 

- ‘Abdu'l-Baha  (Tablets of Abdu'l-Baha vol. 2)
