's believe that work performed in the spirit of service is worship:
"If a man engages 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 the churches and temples."
, quoted in Compilation, Baha'i World Faith
"`Should Prayer take the form of action?'"
`Abdu'l-Bahá.--`Yes: In the Bahá'í Cause arts, sciences and all crafts are (counted as) worship. The man who makes a piece of notepaper to the best of his ability, conscientiously, concentrating all his forces on perfecting it, is giving praise to God. Briefly, all effort and exertion put forth by man from the fullness of his heart is worship, if it is prompted by the highest motives and the will to do service to humanity. This is worship: to serve mankind and to minister to the needs of the people. Service is prayer. A physician ministering to the sick, gently, tenderly, free from prejudice and believing in the solidarity of the human race, he is giving praise'."
