A conjunction is when two planets (or Sun/Moon/Ascendent etc) are right next to one another. Tight means one or two degrees apart from one another. This means the two planets or astro-points in question are absolutely forced to get along and work together.
A conjunction of – say – the Sun with Venus is pretty compatible by nature. Ditto Mars-Pluto – intense, but the two have mega affinity. A conjunction of Moon-Saturn is not so simple to manage but the struggle is what makes one.
So go to thy chart and find your most exact conjunctions. I am talking within three degrees max. And then that tightest conjunction + the house (area of the chart) it is in is who you are…
Have fun and I will pop into the comments if i get the chance.
