Artha, Kama and Moksha Yogas

@ernst,

With regards to these dharma, artha, kama and moksha yogas, would we give precedence to a raj yoga if we see a classical raj yoga happening (dharma yoga) vs. the others? 

Also, for a virgo lagna, if Sa is in an angle, would that also be a dharma yoga despite the fact that for Virgo lagna, Sa is not a yogakaraka?

Thanks!
