In the Bahá'í Faith, "Satan" is not regarded as an independent evil power as he is in some faiths and religions, but rather signifies the "lower nature" of humans. `Abdu'l-Bahá explains: "This lower nature in man is symbolized as Satan — the evil ego within us, not an evil personality outside." All other evil spirits described in various faith traditions—such as fallen angels, demons, and jinns—are also metaphors for the base character traits a human being may acquire and manifest when he turns away from God. Actions, that are described as "satanic" in some Bahá'í writings, denote humans deeds caused by selfish desires.
