The following represent the core values or principles of the Baha'i Religion according to Dr. Leland Jensen which were first explicated by `Abdu'l-Baha:
1. "The Oneness of the World of Humanity." "Hands may be black, white, yellow, or brown, but the hue of the heart is one." The first foundation stone is the jasper ; it is a clear red, like the hue of the heart. In ancient times it was called the bloodstone.
2. "The Independent Investigation of Truth." All must be free to seek out truth in their own way. The second foundation stone, the sapphire, is a clear blue, 'true blue,' and the color of faith, inspiration, loyalty and truth. Man must be free to soar in this "Dome of Heaven's blue truth," and see it with his own eyes.
3. "The Foundation of all Religions is one." Each Revelator has given the same "New Heaven and Earth" but man has polluted and misrepresented these Divine Laws. In reality, they are all one. The third foundation stone, the chalcedony , is pure white, of which Ábdu'l-Bahá said: "While white is apparent, yet in it is hidden and concealed the seven colors. In white all colors are brothers and sisters." White is the symbol of purity, and in its origin each religion is pure, and a brother to every other religion, for all Truth is one.
4. "Religion Must Be the Source of Unity." If it is not, its non-being were better than its being. The fourth foundation stone, the emerald, is green . Green is the color of harmony and unity. There is no color known that green will not harmonize with, as the green foliage blends with every hued flower. It is the color of immortality and also of humility.
5. "Religion must be in accord with Science and Reason." Neither must deny the other. The fifth foundation stone, the sardonyx, is red or brown, according to the way it is held. as it is with science and religion; they are in essence one, but differ in color of manifestation. Today they are coming closer together in their realities in the minds of thinking people.
6. "The Equality of Men and Women." They must be as the two wings of the soul, each equally developed. The sixth foundation stone, the sardius, is a stone in two layers, one white and one red, symbolic of the two in one who unitedly further the progress of mankind.
7."Removal of all Prejudice; Religious, Racial, National, Political, etc." The seventh foundation stone, the pure chrysolite, is exquisitely clear, slightly tinted green. We read in the ancient philosophies of the Chrysolite Tablet that it is the symbol of absolute sincerity and truthfulness, purity and selflessness. Only when our hearts are free from every form of prejudice can they become the 'chrysolite tablet' wheron may be engraved our thoughts and motives.
8. "Universal Peace." The eighth foundation stone, the beryl, isgreenish-blue ; somewhat like the ocean wave as it mounts toward its crest, the blue of faith and loyalty toward our brother man, the green of humility and unity, the harmonious blending into one symmetrical whole, like a beautiful bouquet of flowers. This established in the hearts of man, will also establish Universal Peace.
9. "Universal Education." The ninth foundation stone, the topaz, the glory of the sun, is symbolic of the light of knowledge and the glory of wisdom, which universal education will establish in the world when the golden topaz, Light of the Teachings of Bahá'u'lláh, is understood and lived.
10. "The Spiritual Solution of the Economic Problem." The tenth foundation stone, the chrysoprasus, is like opaque chrysolite, a clear green which embodies truthfulness, justice, sincerity and purity, and these are the requisites necessary for the solution of all economic problems-the Golden Rule-"Do unto others as ye would that they would do unto you."
11. "A Universal Language." The eleventh foundation stone, the jacinth, is somewhat like the jasper, rose red, the universal color, the hue of the heart. A race can only understand the heart of another when it can speak the same language.
12. "An International Tribunal, or Parliament of Nations---The Universal House of Justice with the Davidic Guardian." The twelfth foundation stone, the amethyst , is violet. It symbolizes spiritual light--reverence, healing, serenity, and poise. This Tribunal of all nations must be as the ultraviolet rays for the 'healing of the nations' and it must seek spiritual light in all reverence, that it may fulfill its high calling, imparting a sense of security, poise and serenity to the hearts of all humanity.
`Abdu'l-Baha taught this doctrine as recorded in pilgrim's notes relayed at http://bahai-library.com/books/apocalypse/appendixg.html (accessed 8/5/2011)
The above explanation of the twelve foundation stones was purportedly given to Shanaz Waite by 'Abdu'l-Baha. It should be considered a "pilgrim's note" and therefore, not an authentic Writing. This version of the pilgrim's note was obtained from Flora Brooks, a Baha'i of Staunton, Virginia, who obtained it from Ruth Moffett.
