9 grahas…..

we have 9 grahas.
sun and moon are the luminaries(our energies & emotions)
Rahu and ketu are the desired(new thing to learn) and undesired(we are already good at)
other 5 grahas controls the conditions and events external and internal to us.
lagna is our physicality and personality.
if we are in full control of our enegry,emotion and what we want and dont want in life
do we really need to worry about the jupiter,saturn,venus,mercury and mars ?
