Astrology

O handmaid of God! The stars in the sky do not exert any spiritual influence on this world of dust; but all the members and parts of the universe are very strongly linked together in that limitless space, and this connection produceth a reciprocity of material effects. Outside the bounty of the Holy Spirit, whatsoever thou hearest as to the effect of trances, or the mediums' trumpets, conveying the singing voices of the dead, is imagination pure and simple. As to the bounty of the Holy Spirit, however, relate whatsoever thou wilt -- it cannot be overstated; believe, therefore, whatsoever thou hearest of this. But the persons referred to, the trumpet-people, are entirely shut out from this bounty and receive no portion thereof; their way is an illusion.

Question. -- Have the stars of the heavens any influence upon the human soul, or have they not?

Answer. -- Some of the celestial stars have a clear and apparent material effect upon the terrestrial globe and the earthly beings, which needs no explanation. Consider the sun, which through the aid and the providence of God develops the earth and all earthly beings. Without the light and heat of the sun, all the earthly creatures would be entirely nonexistent.

With regard to the spiritual influence of stars, though this influence of stars in the human world may appear strange, still, if you reflect deeply upon this subject, you will not be so much surprised at it. My meaning is not, however, that the decrees which the astrologers of former times inferred from the movements of the stars corresponded to occurrences; for the decrees of those former astrologers were forms of imagination which were originated by Egyptian, Assyrian and Chaldean priests; nay, rather, they were due to the fancies of Hindus, to the myths of the Greeks, Romans and other star worshipers. But I mean that this limitless universe is like the human body, all the members of which are connected and linked with one another with the greatest strength. How much the organs, the members and the parts of the body of man are intermingled and connected for mutual aid and help, and how much they influence one another! In the same way, the parts of this infinite universe have their members and elements connected with one another, and influence one another spiritually and materially.

‘Abdu’l-Bahá, Some Answered Questions, p. 244

...it is absolutely essential that the teachings should not be confused with the obscure ideas related to numerology . . . and the like. Individuals interested in them are free to believe in and credit such ideas and to make any inferences and deductions they desire from them, but under no circumstances are they expected to identify them with the principles and teachings of the Cause.

Shoghi Effendi, Spiritualism, Reincarnation and Related Subjects, pp. 9, 10

Astronomy is a science, astrology does not come under the same category, but we should be patient with people who believe in it, and gradually wean them away from reliance on such things.

Shoghi Effendi, Lights of Guidance, p. 515

Concerning your question as to the influence of the stars and planets on the life of a believer; such ideas should be entirely dissociated from the Teachings. The passage on p. 133 of the 'Gleanings' bears no reference whatsoever to this matter. As to illness or poverty; such calamities may be either irrevocable or, and it is often the case, they may be avoided. There is no reference in the Teachings as to whether the stars have any influence on healing such diseases. These astrological ideas are for the most part sheer superstitions.

Shoghi Effendi, Spiritualism, Reincarnation and Related Subjects, pp. 9, 10

The friends should be encouraged not to waste time on such things as astrology, etc., which you mention. They cannot be forbidden to do so. The exercise of our free will to choose to do the right things is much more important.

Shoghi Effendi, Lights of Guidance, p. 516

We should attach no importance to astrology or horoscopes. No exact science is involved, though sometimes some truth seems involved, but the percentage is small.

Shoghi Effendi, Lights of Guidance, p. 516

You ask for guidance in answering questions put to you about African traditional astrologers, and so-called "bad spirits". We are directed to convey the following. Bahá’ís should be encouraged to preserve their inherited cultural identities, as long as the activities involved do not contravene the principles of the Faith. When such activities are not in accord with the teachings of the Faith and have been established among communities for centuries, weaning the Bahá’ís from them is a gradual process and takes time and patience. Any bad habits of ancient cultural traditions are overcome by the offering of a greater spiritual attraction. As the new believers become more and more attracted to Bahá’u’lláh and His teachings, they are more likely to be able to turn away confidently from old ways that are in disagreement with His teachings.
