Yods are funny little creatures...they're not Universal and not everyone has one.
They're an Aspect pattern in the chart where 3 planets are linked together in an isosceles triangle.
The Yod links three Elements that don't get along. The degrees are 2x inconjuncts (quincunx) and one sextile aspect.
at William's chart. He has his Yod linking his Venus, Pluto and Neptune.
Big Thanx to Michael for this chart today:) xx
The symbol for a Yod looks like a little table with an A for its legs.....but like a wall-paper pasting table...
More info is in Karen Hamaker-Zondag's wonderful book The Yod Book, including a complete discussion of unaspected planets
