Gāndhārī was so faithful, one of the most exalted, chaste wife mentioned in the śāstras, Gāndhārī, that in all condition she followed the husband. At last, when everything was finished in the Battle of Kurukṣetra—no Kaurava, none of the sons or grandsons of Dhṛtarāṣṭra was living, neither of the Pāṇḍavas—still, Gāndhārī was faithfully serving her husband. And Dhṛtarāṣṭra was living with the nephews, Yudhiṣṭhira and his brothers. They were keeping the uncle very comfortably as elder uncle, all respect. But Vidura came there, and he criticized him, that "You have no shame. You all along remained enemy to your nephews. Now your nephews have killed all your descendants, and you are living here just like a dog. They are giving you some morsel of bread and you are eating and living here. You have no shame. You have become old."
So he became very sorry, "My dear brother, what shall I do?" "Please come immediately along with me, and come to the forest." So Dhṛtarāṣṭra went, according to the instruction of Vidura. Gāndhārī followed. Gāndhārī never said that, "I am now old. I have lost my children. These nephews, they're taking care of me. Why shall I go with my husband?" No. She also went. So there are many good qualities in Mahābhārata about Gāndhārī. Therefore she is described here as tapasvinī. Tapasvinī. Very chaste, faithful wife. Ideal wife. Gāndhārī. Tapasvinī.
