Analogy VENUS / NEPTUNE

The Yod symbolises a major event in a person's destiny. The planet on the receiving end of the Yod's energy symbolises the sector of life needing to be transformed, where creativity is often blocked. The planet receiving this energy symbolises the area in which an important decision will need to be made and the House involved defines which area (for example, the Second House = material concerns, the Seventh House = relationships, etc.)"

via "The Yod pattern: In the natal chart & by transit":

"Finally, and that is quite interesting, anyone can have a Yod by transit, creating the same conditions as a natal Yod. If you have a sextile in your chart (within 3 degree orb), every time a planet transit the 150° apart, you have a quincunx by transit. Equally, if you have a quincunx in your chart (within 3°) every time a transiting planet comes to a sextile to it while being 150° from the natal planet, you have a Yod. The Yod is also possible if two transit planets happen to form a Yod with a third natal planet. The Yod is also possible with progressed planets."
