This is an interesting diagram which delineates the ‘strength’ of Pluto through the signs. With Pluto, stronger does not mean better, it means, well, stronger. To have sympathy with an energy does not always mean to have more of it, indeed, Pluto is subtle, deep and most of all hidden, so to have Pluto in positive, outgoing and extrovert signs, like Leo, Libra and Sagittarius is uncomfortable for Pluto, who enjoys Scorpio for precisely the reason that he can remain subtle, deep and hidden.
But there is a way in which stronger does mean better, provided you can utilise the lessons of Orcus and find true spiritual integrity. In this way you will not be ‘broken’ by Pluto. So if you have Pluto strong then you are facing a major test in this incarnation, and one which you will learn at a much greater personal cost (but also a cost to those in your life) than the majority whose Pluto’s are less ‘out there’.
If you have Pluto close to an angle, then he becomes even stronger, and he is also strong in the 5th, 7th and 9th houses. So if you have Pluto rising in Libra or Sagittarius, and to a slightly lesser extent Leo, then know that you have quite a trip ahead of you and you need, for the sake of your eternal soul, to get down to some serious spiritual work if you want to avoid the burden of a lot of karmic payback as well as realise the not inconsiderable benefit of having transformed a great deal of Hadean force. That will make you quite formidable, but in a loving and meaningful way.
Plus, what choice do you have? Any other road leads only to unhappiness.
