Yod

yod

Definition

A Yod is an aspect pattern in which two planets in sextile (60°) each form a 150° quincunx to a third planet, drawing a narrow, tall triangle on the chart wheel. It is also called the 'Finger of God.' The apex planet sits where the two long sides meet; the point directly opposite the apex is the reaction, or release, point. The usual orbs are 7° for the sextile and 3° for each quincunx.

In Tradition

Most Western astrologers tie the Yod to a sense of fated adjustment and awkward timing. The two quincunxes converging on the apex create a steady pressure to change, with no obvious way forward — because the signs they link share no element, mode, or polarity.

In Practice

To read a Yod, astrologers name its parts: the apex planet, the two base planets joined by the sextile, and the reaction point opposite the apex. The apex planet's sign and house mark where the adjustment pressure gathers. As slow outer planets move into contact with the apex or the reaction point, they light up the whole pattern. When a fourth planet sits on the reaction point, directly opposite the apex, the figure becomes a Boomerang, which gives the pattern a concrete point of balance.

Historical Origin

The Yod is a modern named aspect pattern, with no trace in ancient or medieval texts. The quincunx itself had no place in the Ptolemaic system — Hellenistic astrology counted it as aversion rather than an aspect. The Yod as a named figure took shape in 20th-century literature.
