"Astrology is worthless and this is why it is indispensable". I think that the issue with this work can be traced back to this sentence. Astrology could be useful, and aimed solar revolutions are an essential tool to really revolutionize your life for the better. And you should pay attention to where the Ascendant and the other planets fall in the Solar revolution's chart, this is to say the houses, and not the signs. And, apart from Jupiter and Saturn, Mars shall be taken into account as well as a very important planet in ASRs (Aimed Solar Returns). Some insights are brilliant, like the way Jupiter expresses itself in Pisces, or the distinction between Saturn in Capricorn vs. in Aquarius, or the one attributed to astrologer Lu Gaitán (the "autopredictions") but in my opinion they are not sufficient to justify a book that had the noble aspiration to free the readers from their own "cages" but that, actually, does not provide them with more concrete tools to do that for real. As an astrologer who belongs to the Active Astrology school I do believe that Astrology can be a very useful tool.
