If Langit needed a month for him to be absolutely sure to let Kertabumi go, then Wisnu, as the husband of that woman, needed even more time. If he had followed what he had planned before, he should have returned to asceticism after Kertabumi gave birth.
However, when he saw the child being born and his wife becoming a mother, he was moved. Wisnu did not have the heart to leave Kertabumi alone.
At least, he needed six months until he was absolutely sure to leave his beloved wife. Wisnu really, really wants to look after Kertabumi, even though the woman has said many times since their child was three months old that Wisnu can go into meditation again if he wants.
But the young man did not do it at all. He didn't even want to leave the house at all, and the whole babysitting business was completely left to Wisnu.
