Raja Yoga in 11th lord Dasha when it's conjunct/mutual aspecting 10th lord?
In Vault of the Heavens, you mention -
"If the 10th and 11th lords join or aspect each other, Raja Yoga will
be caused in the dasa of the 11th lord;"
Can you please shed light on how and why this occurs?
In Bhavarthna Ratnakara text there are dasa effects of particulary conjunctions, where one planet gives the effect in its dasa and the other planet does not give its good effects So if 10th and 11th lords are joined or aspected, the good stuff will happen in the dasa of the 11th lord, not the dasa of the 10th lord, if an astrologer did not know this, he would predict both 10th and 11th lords dasa and be wrong on the 10th.
