Avoid Too Great a Variety of Mental Food—God would have the mental faculties kept pure and clean. But often too great a variety of food is given to the mind. It is impossible for this to be properly taken care of and used. The brain should be relieved of all unnecessary burden. Only the studies which will be of the most use not only here but in the future life, which will provide the best instruction for body and soul, will be carried over into eternity.— Manuscript 15, 1898. {1MCP 194.3}

Undgå for stor variation af intellektuel føde. - Gud vil at de intellektuelle evner holdes pure og rene. (195) Men for ofte får sindet en stor variation af føde. Men det er umuligt at tage hensyn til dette altid. Hjernen bør lettes for alle unødige byrder. Kun de studer som bruges allermest, ikke kun her men i det fremtidige liv, som giver legemet og sjælen den bedste undervisning, vil føres over i evigheden. - MS 15, 1898.
