In the Purans, they mention his wives, and they give rise to two sons.

So they are called Kshem and la'b.

Kshem is also called Shubh. So Shubh, we know, is auspicious or welfare.

And la'b is profit.

Only when you act with wisdom, with knowledge, with patience, and you analyze all the aspects, only then you can get profit, only then you can get your welfare.
