yep i knew about it, read up a fair bit alongside with 1001 field of studies. but i don't particularly buy into it, especially in the realm of fortune telling (i prefer the more accurate guidance of the Holy Spirit). I do note the particular attributes that goes to a person based on their birth hour ~ but that seemed to me more like a collective data of statistics, pretty much similar to ~ a certain group of people displaying certain characteristics. It does have a degree of truth in it, but thats pretty much like weather forecast - higher chance of accurate 'prediction' when the day comes nearer, but anything can happen, and weather is in itself the most unpredictable.
i would definitely not tossed the field of studies into the bin as 'total nonsense' because it is indeed a profound study by itself ~ the question is, how do we use this data? Many people who do not know any better might be 'misled' and hence theres the general opinion that 'dabbling with the "occult" can be dangerous'. I'd also researched into tarot cards, and used to do readings for people.
