Jackal

Upon hearing the jackals crying in the forest of Vṛndāvana, Mother Yaśodā sometimes became very careful about keeping Kṛṣṇa under her vigilance, fearing that Kṛṣṇa might be attacked by them. This is an instance of ecstatic love for Kṛṣṇa in fearfulness caused by a tumultuous sound. This kind of fearfulness is a little different from being actually afraid. When one is afraid of something, he can still think of past and future. But when there is this kind of ecstatic apprehension, there is no scope for such thinking.
