This is a square formation of lines appearing on the Jupiter mount. Whenever seen, it indicates the ability to impart knowledge. If this square is analysed it can be seen to be made up of an effort line towards Jupiter and oblique lines crossing the Jupiter mount. The effort line to Jupiter implies that ambition drives the person towards possible academic achievement. The oblique lines across Jupiter indicate perception, sympathy and a humanitarian view towards other people. When combined, these qualities may indeed point towards a person who has teaching ability with the desire to impart knowledge for the benefit of others.
