The day of Vaishakh poornima is also celebrated as Shri Koorma Avtara day of lord Vishnu. It happened before the spiritual event of Samudra Manthan. He acted as the base of Mandhara Parvata used for Manthan. It is most important here to note that for this purpose to fulfil, goddess Lakshami also joined his turtle form in the form of Shriyantra. So for pleasing Lakshami, it is preferred to worship sriyantra at the back of Turtle form of Lord Vishnu.
Shri Koorma avtara is the incarnation of Lord Vishnu associated with planet Saturn, also called Kachchhap Avtara. So worship of Shri Koorma is performed for getting rid of evil effects of Saturn in life.
