Unselfish ambition, noble life-motives, and purity, — these constituents of thought, mingling, constitute individually and collectively true happiness, strength, and permanence. (Science and Health with Key to the Scriptures by Mary Baker Eddy p58: 7)
Hold thought steadfastly to the enduring, the good, and the true, and you will bring these into your experience proportionably to their occupancy of your thoughts. (Science and Health with Key to the Scriptures by Mary Baker Eddy p261: 4)
Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things. … and the God of peace shall be with you. (The Bible – Philippians 4: 8, 9)
