The best I can suggest is that you get a copy of Jeffrey Wolf Green's, Pluto Volume I, The Evolutionary Journey of the Soul, and read the chapter on 'Transits.' You can also read the relevant chapters on 'Pluto through the Houses' to get an understanding of the primary archetypes and themes of those houses.Transits
-- Transits symbolize critical times from an evolutionary point of view where the core lessons in the natal chart are emphasized to be resolved, and growth is intended to occur in an accelerated/intensified manner. The specific transit will of course reflect the core dynamics to be worked upon. (Deva)
-- To understand any planetary transit, is to understand what the issues and dynamics are for the natal planet in question. Within that to understand the planet’s relationship to the rest of the birth chart from an evolutionary point of view. Why is the planet in this or that house, this or that sign, this or that aspect, etc? In this understanding make sure to include the natal planetary nodes of the planet you are considering. Once the totality of this understanding from a natal point of view is understood then the current position of the transit of that planet correlates to how all those issues and dynamics are being worked through by the house and sign that the planet in question is moving through. (Rad)
-- Transits need to be compared to the bigger picture of the natal chart. Transits relate to the details within that. You always start with Pluto, the Soul, by house and sign, then the Nodes and their rulers.Pluto crossing the Ascendant
Any planet crossing any angle (cardinal) is going to have a strong effect as a natural gateway to initiate action and change.
