Hi Taurus90I also started to use the asteroid Destinn some time ago since i researched in my natal/sinastry/composite and seems to resonate very well.
would think that "Destinn" points naturally to "Fate,karma,meant to be feeling" - but not as too strong as the KARMA asteroid.
I have seen that Destinn appears to be very relevant in relationship charts,at least the ones i looked into:
Me and bf:
VX/Destinn conjunction
Destinn conj AC
PARENTS
Destinn conj Karma/Sun of the other
Jonhy Cash/June Carter
Oneīs Destinn conj otherīs Amor
Oneīs Destinn conjotherīs 8thcusp/Ceres
