Summary: The alchemical term nigredo means black or blackening, and is associated with decomposition and putrefaction. As a psychological state, nigredo is “the great suffering and grief” which the detached forces of nature inflict on the soul. We realize in sorrow that what we thought were truths were illusory. Individuals may have taken pride in their virtues, talents or good fortune; societies may have touted their cultural superiority, military prowess, or wealth.
