Srimad-Bhagavatam: Canto 1 - Chapter 1 - Verse 3


तत्रासीनं कुरुपतिं धृतराष्ट्रं सहानुजम् ।गान्धारीं पुत्रशोकार्तां पृथां कृष्णां च माधव: ॥ ३ ॥


tatrāsīnaṁ kuru-patiṁdhṛtarāṣṭraṁ sahānujamgāndhārīṁ putra-śokārtāṁpṛthāṁ kṛṣṇāṁ ca mādhavaḥ


There sat the King of the Kurus, Mahārāja Yudhiṣṭhira, along with his younger brothers and Dhṛtarāṣṭra, Gāndhārī, Kuntī and Draupadī, all overwhelmed with grief. Lord Kṛṣṇa was also there.


The Battle of Kurukṣetra was fought between family members, and thus all affected persons were also family members like Mahārāja Yudhiṣṭhira and brothers, Kuntī, Draupadī, Subhadrā, Dhṛtarāṣṭra, Gāndhārī and her daughters-in-law, etc. All the principal dead bodies were in some way or other related with each other, and therefore the family grief was combined. Lord Kṛṣṇa was also one of them as a cousin of the Pāṇḍavas and nephew of Kuntī, as well as brother of Subhadrā, etc. The Lord, therefore, was equally sympathetic toward all of them, and therefore he began to pacify them befittingly.
