[estrella]

Yes, I know someone with a large stellium in Leo in the 7th. He is basically a really good guy. But when he was younger he was quite self-absorbed and vain. Very attractive man. Perpetual bachelor, never married. The desire for relationships vs. desire for Independence has been a big struggle in his life. He has the ability to focus his energies very effectively, and has a rather one track mind. Very proud and regal.
I have noticed in many charts that large stelliums can predispose the person toward OCD to some degree, probably due to all that highly focused, concentrated energy.

How the stellium operates of course is reflected in the planets involved, the house(s) involved, and aspects involved. Also, I notice that the tensions related to the stellium can emerge in the opposite house. For example, someone with a strong stellium in the 7th would tend to have that energy spill over into the 1st, making for someone that can be self centered with a tendency toward vanity and fierce independence. When (or if) that person matures, then it becomes possible to deal with the issues indicated by the stellium in a better way.
