…in accordance with the divine teachings the acquisition of sciences and the perfection of arts are considered acts of worship. If a man engageth with all his power in the acquisition of a science or in the perfection of an art, it is as if he has been worshipping God in churches and temples. Thus as thou enterest a school of agriculture and strivest in the acquisition of that science thou art day and night engaged in acts of worship—acts that are accepted at the threshold of the Almighty. What bounty greater than this that science should be considered as an act of worship and art as service to the Kingdom of God.
