This image above is just an example illustrating this type of configuration in a astrological chart.
The Grand Cross consists of four or more planets spread at intervals of approximately 90°. This is a very uncommon byt powerful configuration. A cross or two oppositions is formed in the chart. This configuration generally indicates a person living under continuous stress and facing a seemingly never ending series of challenges. This aspect places your life in a constant state of tension and upheaval. The Grand Cross is very rare. It characterizes an individual who should be concerned with people and personal or intimate relationships, rather than criticism, ideals, and values. It is hard for you to avoid spilling your energies in diverse and related directions. Many obstacles will interfere with the realization of goals.
