MERCURY
Smallest among all the planets but the control which it carries is utmost superior.
Our nervous system.which starts from head spreads in spine and keeps the in and out of every stimulus which we receive .
It perceives the signals using our senses , analyses and quickly gives us the ideas to react.
Please givea thought on the fact :
that what we control is only our REACTION
althugh situation are never under ourcontrol.
So the way we give our reaction to situation will make us genius or fool.
Genius have an idea different so reacts differently.
As in geetaArjuna saw only birds eye.
So the stronger this smallest planet more ideas you have and more you analyse more you are successful.
Mercury i n medical astrology represents our brochus the connectivity (communication) of outer air to our lungs .and sixth sign intestines .our inner connection to Outer world throgh anus.
So to improve mercury
