Some comments
ArcanoMáximo, you said, "Then i started to wonder me how many more Astrologers would be thinking that, even when as we all think here both have the same bases." I would not agree with this statement that both Astrology and Tarot have the same basis!
** Astrology is an interpretive process that uses observed/calculated planet positions and spatial orientations to tell about an event or a birth. Astrology is a science and/or a process that was developed initially some 2000 years ago.
** Tarot is an interpretive process that uses illustrated cards, seemingly random drawn, to provide meditative and divinatory insights in relationship to a given question or concern. Tarot was developed some 500 years ago and evolved into a divinatory format more recently, and incorporates symbology that was common to its founding cultures.
As one who practices both systems, I do not generally engage in both systems for one reading. On another web-site which I co-moderate I have posted both Tarot and Astrology readings on a single subject, currently a predicitive effort concerning the upcoming Iraqi referundum. I have often seen querents seek different answers relative to either an astrological or a tarot reading -- tarot querents often start with a narrow question while, in my experience, astrological querents want a general life/status reading in which to have a context for a specific issue and its timing/progress.
