Mars, the planet of energy, conflicts, and passions when placed in Purva Phalguni, is known to bring about changes in an individual's personality. It is one of the most dynamic nakshatras and is ruled by Venus. As Mars seeks aggression and Purva Phalguni's ruling deity Bhaga seeks enjoyment and pleasures, the combination results in a blend of energies that can be both productive or destructive, depending on other astrological aspects.
