This Indian Express article quotes Devdutt Pattanaik as saying:
On tradition vs modernity
Modern people invent tradition. Because modern people want to feel “liberal” and “modern”, they will construct a past that is conservative. And you see that in writings all the time. So Sita has to be this creature who has no voice of her own. But when you actually read the Valmiki Ramayana, you'll be like, 'this lady seems to have a voice'. In fact, there's a dialogue where Ram says, "Whenever I ask her to do anything, she says no."
Which verse of Vālmīki Rāmāyaṇa is Pattanaik referring to?
