Gandanta point means karkataka last degree and Simha first degree.
Your sun is in 29degrees 7minutes of karkataka.
Your Guru is in 0 degrees 21min of Simha.
Both the planets are in gandanta position.
They are called sandhi points.This is a special sandhi
between Kataka and Simha.
Another gandanta is between Vrishchika and Dhanush.
Sun is alright as it is having Digbala in 10th house.
But Guru in 11 th house is not having strength in your horoscope.
There are 4 planets in 11th house..
