The seven candles, the 20th century, and other questions

[Sen McGlinn]

This video starts with the question, whether Abdu'l-Baha's letter on the "seven candles of unity" describes successive stages (the answer is no). It points to a relationship between the "seven candles" and a section of Abdu'l-Baha's book, "The Secret of Divine Civilization," and to four more paragraphs of the "seven candles" letter that Shoghi Effendi translated, published only in The Bahai World volume 2. And it describes how the supposition that the fifth candle refers to the twentieth Gregorian century has led to misunderstandings and baseless expectations. The "timeline" for the seven candles and the processes of The Secret of Divine Civilization, and the meaning of "the century of light," is the 1000-year dispensation of Baha'u'llah, not the western 20th century.
Incidentally - when Abdu'l-Baha used the image of seven candles, was he referencing the menorah?
