How can I "mitigate" the effects of a Mars/Moon transit to 3rd (and soon 4th!) house?

The moon will be out of there in a couple of days. Not so with Mars. My advice is that you try to avoid any battles with 3rd house issues, neighbors, siblings, and your local neighborhood. Whenever Mars transits a house, there is a greatly increased need for a battle as that is what Mars desires. Mars has to have a battle. However one must really choose proper battles. Make sure the battle is worth the effort . There's no shame in losing a few battles because one wants to win the war! So, stay away from "drama" battles while Mars transits the 3rd house. And it is so easy to get caught up in battles with brothers and sisters. Neighbors too. Keep topics simple and don't go to subjects that are filled with resentment or possible arguments. When Mars transits your 4th house the same principle applies but now you will be deaiing with home and a parent usually your primary caregiver, and activity that happens "behind closed doors." Again keep it light and if you have to battle make darn sure that it is a battle worth fighting.This should help you through these transits. Remember that sometimes it is better to walk away from a fight because so many are not worth the energy. Save your energy for battles that are worthy of your time. Good luck and bless you. You'll survive!
