These illuminating times of boundary crossing into increased wisdom can be predicted when an outer planet such as Pluto, Neptune, Uranus, Saturn, or Jupiter make a close transiting aspect to the gandanta point. At this time, the person will have a chance to untie the knots of karma that leads them to a major breakthrough in consciousness level. However the process can be linked with considerable trauma, struggle, and upheaval, maybe even a dark night of the soul.
I have Jupiter at 29 degrees Pisces in the 9th house and transiting Uranus is currently making a conjunction to it. From my personal experience, and my experience reading thousands of charts with gandanta points, this video is the best description I've come across to date. Please take the time to watch it, I promise it will be insightful.
