“the portrayal of the Báb and Bahá'u'lláh in works of art is forbidden”; “no objection to symbolic representation of such Holy Figures”

Your understanding that the portrayal of the Báb and Bahá'u'lláh in works of art is forbidden, is correct. The Guardian made it clear that this prohibition refers to all the Manifestations of God; photographs, or reproductions of portraits, of the Master may be used in books, but no attempt should be made to portray Him in dramatic or other works where He would be one of the 'dramatis personae'. However, there can be no objection to symbolic representation of such Holy Figures, provided it does not become a ritual and that the symbol used is not irreverent.

Tablets of chrysolite mentioned in the Hidden Words

One of the explanations given today concerned the meaning of the Tablets of chrysolite mentioned in the Hidden Words, about which one of the friends had asked. The Master replied:

“What is meant is one of the holy Tablets. But it also alludes to the fact that the divine Tablets should be engraved on precious stones. In addition, there is a saying in the East by which the color white symbolizes divine will; red, divine decree and martyrdom; green, predestination; and yellow, execution of the decree.”

“The Báb wrote a letter containing three hundred and sixty derivatives of the root Bahá”

The Báb announced that the greater Manifestation would take place after Him and called the Promised One “Him Whom God shall make manifest,” saying that nine years later the reality of His own mission would become apparent. In His writings He stated that in the ninth year this expected One would be known; in the ninth year they would attain to all glory and felicity; in the ninth year they would advance rapidly. Between Bahá’u’lláh and the Báb there was communication privately. The Báb wrote a letter containing three hundred and sixty derivatives of the root Bahá.

Manifestation of God “resembleth the physical sun, His verses are like its rays, and all believers, should they truly believe in Him, are as mirrors wherein the sun is reflected”

Since all men have issued forth from the shadow of the signs of His Divinity and Lordship, they always tend to take a path, lofty and high. And because they are bereft of a discerning eye to recognize their Beloved, they fall short of their duty to manifest meekness and humility towards Him. Nevertheless, from the beginning of their lives till the end thereof, in conformity with the laws established in the previous religion, they worship God, piously adore Him, bow themselves before His divine Reality and show submissiveness toward His exalted Essence. At the hour of His manifestation, however, they all turn their gaze toward their own selves and are thus shut out from Him, inasmuch as they fancifully regard Him as one like unto themselves. Far from the glory of God is such a comparison. Indeed that august Being resembleth the physical sun, His verses are like its rays, and all believers, should they truly believe in Him, are as mirrors wherein the sun is reflected. Their light is thus a mere reflection.

The potency of Baha’u’llah’s Revelation compared to the Báb’s

Better is it for a person to write down but one of His [Baha’u’llah’s] verses than to transcribe the whole of the Bayan and all the books which have been written in the Dispensation of the Bayan. For everything shall be set aside except His Writings, which will endure until the following Revelation. And should anyone inscribe with true faith but one letter of that Revelation, his recompense would be greater than for inscribing all the heavenly Writings of the past and all that has been written during previous Dispensations. Likewise continue thou to ascend through one Revelation after another, knowing that thy progress in the Knowledge of God shall never come to an end, even as it can have no beginning.

“equality of man and woman”: - a unique teaching in the Baha’i Faith

He [Baha'u'llah] establishes the equality of man and woman. This is peculiar to the teachings of Bahá'u'lláh, for all other religions have placed man above woman.

The “high ideals” of the Baha’i Administration

Its[Baha’i Administration] high ideals are "to improve the characters of men; to extend the scope of knowledge; to abolish ignorance and prejudice; to strengthen the foundations of true religion in all hearts; to encourage self-reliance, and discourage false imitation; ... to uphold truthfulness, audacity, frankness, and courage; to promote craftsmanship and agriculture; ... to educate, on a compulsory basis, children of both sexes; to insist on integrity in business transactions; to lay stress on the observance of honesty and piety; ... to acquire mastery and skill in the modern sciences and arts, to promote the interests of the public; ... to obey outwardly and inwardly and with true loyalty the regulations enacted by state and government; ... to honour, to extol and to follow the example of those who have distinguished themselves in science and learning"....”to help the needy from every creed or sect, and to collaborate with the people of the country in all welfare services.” 

- ‘Abdu’l-Baha  (Quoted by Shoghi Effendi in a letter dated 30 January 1926, to the Local Spiritual Assemblies of Iran, translated from the Persian; compilation ‘Agriculture and Rural Life’, prepared by the Research Department of the Universal House of Justice)

“Take pride not in love for yourselves but in love for your fellow-creatures. Glory not in love for your country, but in love for all mankind.”

By the righteousness of the Lord! Ye were created to show love one to another and not perversity and rancour. Take pride not in love for yourselves but in love for your fellow-creatures. Glory not in love for your country, but in love for all mankind.

“heal illnesses by means of foods”

The Báb hath said that the people of Bahá must develop the science of medicine to such a high degree that they will heal illnesses by means of foods. The basic reason for this is that if, in some component substance of the human body, an imbalance should occur, altering its correct, relative proportion to the whole, this fact will inevitably result in the onset of disease. If, for example, the starch component should be unduly augmented, or the sugar component decreased, an illness will take control. It is the function of a skilled physician to determine which constituent of his patient’s body hath suffered diminution, which hath been augmented. Once he hath discovered this, he must prescribe a food containing the diminished element in considerable amounts, to re-establish the body’s essential equilibrium. The patient, once his constitution is again in balance, will be rid of his disease.
