SB Canto 3

Diti prayed for the mercy of Lord Śiva very cleverly. She prayed: "The lord can cause me to cry, but if he likes he can also stop my crying because he is Āśutoṣa. He is so great that if he likes he can immediately destroy my pregnancy, but by his mercy he can also fulfill my desire that my pregnancy not be spoiled. Because he is all-auspicious, it is not difficult for him to excuse me from being punished, although he is now ready to punish me because I have moved his great anger. He appears like a man, but he is the lord of all men.".

SB 3.14.35, Translation and Purport

Let me offer my obeisances unto the angry Lord Śiva, who is simultaneously the very ferocious great demigod and the fulfiller of all material desires. He is all-auspicious and forgiving, but his anger can immediately move him to chastise.
