No other planet symbolizes emotions better than Mars.
Planet Mars is considered as a symbol of energy and vitality. Mars fires your emotions and energizes your passions, but also powers your mental endeavours and communicative skills.
Capricorn is the sign that represents action as it is an active earth sign. As this sign is ruled by Saturn, it is career oriented, about leadership, and success in business.
When Mars transits to Capricorn on December 18th, it brings energy and the ability to work long hours in a selfless mood. There is potential for you, for rapid movement towards obtaining material goals and material things especially in Real Estate and career. It is about new beginnings.
So that day is particularly very important for us in order to pick up the Martial energy, in other words, royalty consciousness.
