Next week however, on Wednesday April 23rd and Thursday 24th, Mars will join them at 13 degrees Libra. This highly unusual line-up of planets is called in astrology a Grand Cross, and usually indicates a state of great tension, stress and conflict, though with the possibility of creative resolution and transcendence. This can come about through finding a deeper common ground beneath the apparent conflict, or by undergoing a paradigm shift in which the conflict no longer assumes the importance it once had. In an individual's natal chart this can, at its worst, be a marker of great inner conflict, and its highest, of genius.
Given the nature of the planets involved and the fact that this is another milestone in the unfolding drama of the series of 7 Uranus-Pluto Squares, this pattern is fraught with potential conflict, though Mars, the astrological significator of aggression, is perhaps at it's weakest at the moment, given that it is both retrograde and in the sign of its detriment, Libra.

The United States is also triggered by this pattern, having its Sun at 13° Cancer and Saturn at 14° Libra. Although both planets are under great stress, the Sun is at least temporarily supported by Jupiter crossing it, whilst its exalted Saturn in Libra may come down firmly on any Martian attempt to threaten its interests.
Let us hope that the tensions already apparent in the lead-up to the Grand Cross will be resolved creatively and intelligently, and that its potential for chaos not be unleashed.
Individuals with planets at 13° of cardinal signs may also be experiencing great tension at the moment, and given that these signs are associated with decisive action, this is the best way of handling such astrological energies. Anything that reduces stress, such as exercise, running, martial arts, sport, dance, massage etc will also help dissipate the tension and avoid unnecessary conflict with others.
