SB Canto 3

Diti was conscious of her offense and was anxious to be excused by Lord Śiva. Lord Śiva has two popular names, Rudra and Āśutoṣa. He is very prone to anger as well as quickly pacified. Diti knew that because of his being quickly angered he might spoil the pregnancy she had so unlawfully achieved. But because he was also Āśutoṣa, she implored her brāhmaṇa husband to help her in pacifying Lord Śiva, for her husband was a great devotee of Lord Śiva. In other words, Lord Śiva might have been angry with Diti because she obliged her husband to transgress the law, but he would not refuse her husband's prayer. Therefore the application for excuse was submitted through her husband. She prayed to Lord Śiva as follows.
