Diti fell asleep during day and also made a mistake in placing her head on the side of the feet while sleeping. Others say that even while Diti sat she fell asleep and she bent her head touching her feet. This was like the contact of brahmana with sudra. That was the cause of her impurity. The other explanations are wrong because it is improper to sleep on bed while one is performing penance. Some others are of the opinion that even while sleeping on the ground the east and south are said to be the proper directions for placing the head according to Smrti text and Diti had slept violating this rule inviting impurity. Seeing Diti Indra laughed. His laughter was due to the futility of her penance and joy due to his success in his effort to find fault with her and punish her.
