Yes that is right Deb, within my chart there is a huge emphasis on mental activity and the mind. 4 of the planets aside from the Moon and Mercury itself are in mind orientated signs also the Sun/ascendant and midheaven.So all these signs are ruled by Mercury then,so we then look at mercury since all these planets in a sense have their energy channeled through mercury.

Also certain houses will be important : 3rd (gemini's natural house) which contains my moon, and also 6th (virgo's natural house) which contains Uranus. Uranus is also at the fated 21st loss degree of Scorpio ,although it is trine to Mercury itself,which probably improves its position. What I usually look at Deb is the depositor chart which shows how the energy gets channeled.This can be found on astro.com >extended chart selection>pullen astrolog> then select 'sign/house depositor graph'.

The one which I find most handy to see the energy at work is the one called 'Sign depositor wheel.' which is in the bottom left.

 

Here with my depositor chart we can see the energy dosn't end with a final depositor,infact its in a loop through the Sun-Moon-Mercury,this sometimes means I go over things a little before I make a decision,for instance sometimes I react emotionally(Moon) to something I may have read (Mercury) which in turn affects my Ego (Sun).once I then think about this though and become aware of the pattern I then often then react differently.like if I read about something in an email that made me angry I often will go over things before I respond so I don't alienate others.
