Samudra manthan
In the Vayu Purana, the legend of Samudra manthan is only briefly mentioned. Kurma is not mentioned in this account or seemingly at all in this Purana. Otherwise, the allegory of the tortoise drawing in its limbs is made at least twice in regards to withdrawing passions and desires (Part 1: 11.19-22 and Part 2: 31.93).
