Mars represents Men.
So Mars is activated:
When you use your aggression.
When you are around other men.
When you invoke your power.
When you use your drive.
When you feel sexual.
So Mars encompasses what it means to be a Man.
Therefore where he is placed within a Man’s chart represents what kind of a Man he has been born as.
Most easily can be seen when around other men.
So when a group of guys get together, their Mars energy becomes invoked and instead of their Soul being the main active part of themselves, Mars will be seen more vividly.
And his above traits inflamed :-)
