Composite Pluto in Eighth House

The effect of Pluto here is to simply reinforce itself, so it will not be as likely to dominate the rest of your relationship as it would in other places. If this is a sexual relationship, it will be that much more intense and allow you to transform sexuality into a conduit to the spiritual of the first order if you choose to pursue that course. If not, it will remain dormant and not get in the way. In a professional context, this will make the use of financial resources from outside the relationship a matter of some contention, and it would probably be a good idea to be careful before you put your eggs in someone else's basket because disputes over the control of them could easily prevent them from hatching. Where you have close genetic or social connections to the past, they will have a compelling influence on you and you may find that this relationship is the key to your inner past in the most profound manner. You may take care to not get too involved with what you believe to be your personal or cultural past because there can be great sensitivity here, and you can feel threatened by large imaginary issues. What seems to be associated with karma, reincarnation, racial past, and other root issues can be more of a personal power and insecurity trip than you may imagine, and you can cross swords with those who do not deserve the association you may attach to them.
