How different is it from the Sagittarius Sun?
Alan Oken take on Sag rising can be inspiring:
A person with Sagittarius rising is devoted to his aims and to the realization of his inner truth. He undertakes his journeys and adventures in order that these subjective realities may be fulfilled in his outer life through a concrete form of expression. Jupiter, the traditional ruler of this sign gives Sagittarius the urge for expansive experiences but it is the Earth, the esoteric ruler of this sign that commands. The Earth requires that one’s ideals and dreams be concretized and made practical. Service is not only an idealistic vision. On the Path of soul-influsion, service has to be anchored in one’s daily life. Sagittarius rising has as its purpose the need to find and formulate a “field of service”, through which one’s abundant creative fires of mind may take root and flourish. In this respect, Sagittarius rising becomes a Knight who holds on to his quest and purpose no matter what obstacles may assail him. His “shining armor” is the Light of the Soul and his purpose is to find the Hold Grail.
