Krishna, once annoyed mother Yashoda to the extent that she attempted to bind Him with a wooden mortar. Yashoda did not know that her child was the Supreme Personality of Godhead Who is unlimited and all-pervading. Although Lord Krishna Himself is the whole cosmic manifestation and beyond the reach of all senses, being compassionate towards His devout mother, He allowed Himself to be bound by her with ropes.
During the course of this leela (often referred to as ‘Damodar leela’) in Vaishnav literature, two demigods, who, under a curse of Narada, were standing as trees in the court-yard of Yashoda and Nanda, got liberated from their curse and assumed their original effulgent forms.
