The trine of Jupiter and the South Node points to an old resource of luck, knowledge, social position, faith, authority, prosperity, or the ability to see life broadly. The person may come into the world with an inner feeling that opportunities exist, help will be found, and space will widen at some point. This is not necessarily wealth from birth, but there is often a natural faith in growth and an ability to attract support.
The South Node shows that the Jupiterian theme is already familiar. In the past or in family memory there may have been education, high status, a religious or philosophical role, mentoring, managing people, life in prosperity, connections with law, foreigners, culture, teaching, or charity. In this life the person can easily use this reserve, especially if the house of Jupiter and the South Node is actively involved.
