What's in a name? Or a chart, for that matter? Here are two charts for a fellow named Ramana Maharshi. Ring a bell? If you recognize the name, then it says heaps and heaps. If you don't recognize the name, then it is likely just some funny foreign sounding name. Just the same way, these two charts provide key vantages in Jyotish for grasping the essential character of a person. If you know some Jyotish and recognize what the circled items stand for then, again, the "name" says a lot. Otherwise, the charts just look like some variant of a skewed tic-tac-toe game.
The goal here is not to get inundated by endless symbols and minutia that can have no practical relevance to anyone outside of an astrologer. Instead, tease out the essential few facts that make all the difference. And run with that.
