Sometimes there is humility due to shyness. For example, when Kṛṣṇa stole all of the garments from the gopīs while they were bathing in the river, all of them begged Kṛṣṇa not to commit this injustice upon them. The gopīs addressed Him thus: "My dear Kṛṣṇa, we know that You are the son of Nanda Mahārāj and that You are the most beloved of all Vṛndāvana. And You are very much loved by us also! But why are You giving us this trouble? Kindly return our garments. Just see how we are trembling from the severe cold!" This humility was due to their shyness from being naked before Kṛṣṇa.
Guilt
When a person blames himself for committing an inappropriate action, his feeling is called guilt.
One day Śrīmatī Rādhārāṇī was churning curd for Kṛṣṇa. At that time the jeweled bangles on Her hands were circling around, and She was also chanting the holy name of Kṛṣṇa. All of a sudden She thought, "I am chanting the holy name of Kṛṣṇa, and My superiors—My mother-in-law and My sister-in-law—may hear Me!" By this thought Rādhārāṇī became overanxious. This is an instance of feeling guilty because of devotion to Kṛṣṇa.
