Synchronicity is a concept introduced by analytical psychologist Carl Jung "to describe circumstances that appear meaningfully related yet lack a causal connection". Synchronicity experiences refer to one's subjective experience whereby coincidences between events in one's mind and the outside world may be causally unrelated, yet have another unknown connection. Jung held this was a healthy function of the mind, that can become harmful within psychosis.

Astral configurations in astrology represent for Jung an example of synchronicity, that is, of a parallel, non-causal relationship between the development of celestial phenomena and those marked by terrestrial time.

Analytical psychology is a term coined by Carl Jung, a Swiss psychiatrist, to describe research into his new "empirical science" of the psyche. It was designed to distinguish it from Freud's psychoanalytic theories as their seven-year collaboration on psychoanalysis was drawing to an end between 1912 and 1913. The evolution of his science is contained in his monumental opus, the Collected Works, written over sixty years of his lifetime.
