When Kṛṣṇa returned from the forest of Vṛndāvana, Mother Yaśodā was so emotional from seeing her son that milk began to flow from her breasts. This is an instance of emotion caused by seeing a dear object.
In the Tenth Canto, 23rd Chapter, 13th verse of Śrīmad-Bhāgavatam, Śukadeva Gosvāmī informs King Parīkṣit: "My dear King, the wives of the brāhmaṇas were usually very much attached to the glorification of Kṛṣṇa, and they were always anxious to get an opportunity to see Him. Because of this, when they heard that Kṛṣṇa was nearby, they became very anxious to see Him and immediately left their homes." This is an instance of emotional activity caused by the presence of someone who is very dear.
When Pūtanā, the demoniac witch, was struck down and killed by Kṛṣṇa, Mother Yaśodā was struck with wonder and began to cry emotionally, "Oh, what is this? What is this?" When she saw that her dear baby Kṛṣṇa was playing on the chest of the dead demonic woman, Mother Yaśodā, at a loss what to do, began to walk this way and that. This is an instance of being emotional on account of seeing something ghastly.
When Kṛṣṇa uprooted the two arjuna trees and Yaśodā heard the sound of the trees crashing down, she became overcome with emotion and simply stared upwards, being too bewildered to know what else to do. This is an instance of being emotional from hearing a tumultuous sound.
When there was a forest fire in Vṛndāvana, all the cowherd men assembled together and desperately appealed to Kṛṣṇa for protection. This is an instance of emotion caused by fire.
