Thats true, but the fact that Rand loves three seperate women suggests to me that she isnt linked to him at all. How many legends are there of Birgitte, Gaidal Cain and some other guy?

 

Well, with the sister bond that the three have and share....could it be that they are considered one?

If the souls are tied together they don't necessarily have to be in love every single Age.  Birgitte and Cain may just be a special case like the twins that are always born together every new Age.

One as in the same soul? No; souls are not born as 2 or more people.

One as in same family? maybe.

 

And just Elayne & Aviendha have the 'sister bond'.  The ceremony has not yet been performed with Min.
