Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 2


भीष्मं कृपं सविदुरं गान्धारीं द्रोणमेव च ।तुल्यदु:खौ च सङ्गम्य हा कष्टमिति होचतु: ॥ २ ॥


bhīṣmaṁ kṛpaṁ sa viduraṁgāndhārīṁ droṇam eva catulya-duḥkhau ca saṅgamyahā kaṣṭam iti hocatuḥ


The two Lords met with Bhīṣma, Kṛpa, Vidura, Gāndhārī and Droṇa. Showing sorrow equal to theirs, They cried out, “Alas, how painful this is!”


Śrīla Śrīdhara Svāmī points out that those who were involved in the assassination attempt were of course not at all sorry to hear of the Pāṇḍavas’ death. The persons specifically mentioned here, however — Bhīṣma, Kṛpa, Vidura, Gāndhārī and Droṇa — were actually unhappy to hear of the supposed tragedy.
