They said, Sukanyâ, in what respect are we incomplete, in what respect imperfect?' The Rishi himself answered them,--'In Kurukshetra yonder the gods perform a sacrifice and exclude you two from it: in that respect ye are incomplete, in that respect imperfect!' And the Asvins departed forthwith, and came to the gods, as they were performing a sacrifice, after the chanting of the Bahishpavamâna.
