In Hinduism, Shakambhari is an incarnation of Ishwari, consort to Shiva. She is the divine mother, 'The Bearer of the Greens'.
It is said that in times of famine, Goddess Durga comes down and gives vegan food, (Shaka comes from Sanskrit. means vegetables and vegan food. Ambari means one who wears or bears), to the hungry. That is why she is called "Shaka" + "Ambari" = 'Shakambhari'.
