This is a very good aspect. According to Haydn Paul Saturn trine Pluto indicates that you will have a good organizing ability,using your concentrated will-power to make the maximum use of your talents and resources, provided that you have clearly defined your purposes in the light of your real potential. The concept of a manipulator of energies – or magician – is evident; and you will naturally use subtle energies to help achieve your will; this may be applied either consciously with deliberation, or as an unconscious psychological projection or emanation from you. This ability can be developed through forms of self-training; and you are likely to be attracted to occultism, astrology, magic, yoga and science, appropriate areas in which to investigate subtle energies through personal experience.
You may have a sense of underlying purpose in your life, perceived as a fated path which is unfolding naturally from within you, yet is a path that you feel you have to follow towards an unknown destination.It can be that this meaningful path of purpose threading through your life has the effect of stimulating essential change and transformation in the lives of yourself and others, and is a ‘calling’ from the trans-personal dimension as reflected by Pluto. You are capable of handling wisely any leadership or managerial responsibilities that you achieve; and you should be able to obtain the co-operation of others by your sensitivity to their feelings and openness to their ideas. Basically, you value people and have respect for others; and you use your powers of persuasion not to abuse the trust of others or take personal advantage, but to develop constructive harmony. You accept the inevitability of change in life, especially in social spheres; and you may apply your talents to social transformation. You are less accepting of change in your intimate relationships, however, as you prefer things to remain in the same pattern once it has been satisfactorily established. You may feel inclined to use your ‘subtle forces’ to protect and restrict such a relationship; and whilst it may be quite protective in effect, you do have to remember the necessity for personal growth and development, and that an atmosphere of mutual freedom is preferable. If you choose your partner wisely, there is the potential for a relatively stable partnership to develop, where both can unfold their unique potentialities over many years."
Also, according to Robert Pelletier “the trine from Saturn to Pluto gives you the power of concentration. Instinctively you know how to manage your affairs for the most benefit. Your thinking is organized, your purposes are realistic, and your attention to duty guarantees success. You recognize that social changes are inevitable. You accept your responsibilities, knowing you can make an effective contribution and can participate in making productive changes in society. You have the determination and persistence to succeed in any field in which management skills are essential. Because you consider carefully other people’s values and feelings, you’re better able to make decisions based on all the available facts. You can effectively manipulate individuals to achieve broad social changes, but you are impatient with those who without trying say they ‘can’t do this’ or ‘can’t do that’.
You are especially capable of handling the resources of a large industrial or social enterprise. In promoting and establishing programs for the benefit of everyone, you try to use public resources. You can stimulate government agencies to assist people in financial difficulties or those who are unable to help themselves. You may seek a government position to better serve those who rely on your talents and persuasive abilities. Your efficiency may even stir your colleagues to assist you in reducing governmental waste. Because you are aware of what is useful and what is not, you might also serve the public by reducing expenditures and thus lowering taxes. You have the power to transform the apathy of youth to excited participation in the affairs of their environment. You can dramatize to adults how their lethargy and indolence has resulted in depletion of public resources. You have much to offer, and you should make it available, for you know what’s right and what’s wrong with society."
This trine is balancing aspect in this chart, since it can make this become aware of what motivates him and it can help verbalizing it, considering the Mercury dispositor. Venus is dispositor of Pluto, so that the personal and even public engagement can have a creative twist to it, revolving around establishing values. Pluto in the fifth is creative and can have a healing effect on hard-aspected Saturn and Neptune. This person is good at regenerating hope. Did you have any more specific questions about this chart?
