Srimad-Bhagavatam: Canto 7 - Chapter 1 - Verse 34
त्वया कृतज्ञेन वयं महीपतेकथं विना स्याम सुहृत्तमेन ते ।तत्रानुयानं तव वीर पादयो:शुश्रूषतीनां दिश यत्र यास्यसि ॥ ३४ ॥
tvayā kṛtajñena vayaṁ mahī-patekathaṁ vinā syāma suhṛttamena tetatrānuyānaṁ tava vīra pādayoḥśuśrūṣatīnāṁ diśa yatra yāsyasi
O King, O hero, you were a very grateful husband and the most sincere friend of all of us. How shall we exist without you? O hero, wherever you are going, please direct us there so that we may follow in your footsteps and engage again in your service. Let us go along with you!
Formerly, a kṣatriya king was generally the husband of many wives, and after the death of the king, especially in the battlefield, all the queens would agree to accept saha-māraṇa, dying with the husband who was their life. When Pāṇḍu Mahārāja, the father of the Pāṇḍavas, died, his two wives — namely, the mother of Yudhiṣṭhira, Bhīma and Arjuna and the mother of Nakula and Sahadeva — were both ready to die in the fire with their husband. Later, after a compromise was arranged, Kuntī stayed alive to care for the little children, and the other wife, Mādrī, was allowed to die with her husband. This system of saha-māraṇa continued in India even until the time of British rule, but later it was discouraged, since the attitude of wives gradually changed with the advancement of Kali-yuga. Thus the system of saha-māraṇa has practically been abolished. Nevertheless, within the past fifty years I have seen the wife of a medical practitioner voluntarily accept death immediately when her husband died. Both the husband and wife were taken in procession in the mourning cart. Such intense love of a chaste wife for her husband is a special case.
