Quote #4
INDY: I think that somebody believes the good luck rock from this village is one of the lost Sankara stones.
The Sankara stones are likely inspired by Shiva Lingam stones, which some believe can boost a man's virility and fertility.
Quote #5
WILLIE: Magic rocks? My grandpa was a magician. He spent his entire life with a rabbit in his pocket and pigeons up his sleeves. He made a lot of children happy and died a very poor man. Magic rocks. Fortune and glory. Sweet dreams, Dr. Jones.
Willie is used to "magic" being a sideshow act. However, there is no rational explanation for the events she will witness in Pankot Palace. They are all supernatural in nature.
Quote #6
INDY: The legend says when the rocks are brought together, the diamonds inside them will glow.
Because diamonds don't actually glow (at least not until Kay Jewelers makes a scientific breakthrough), this line sets up the stones are something magical. Plus, it foreshadows the incantation Indy will chant at the end, making the stones not just glow but burst into flame like hot potatoes.
