SB 10.57.2
bhismam krpam sa viduram
gandharim dronam eva ca
tulya-duhkhau ca sangamya
ha kastam iti hocatuh
Translation:
The two Lords met with Bhisma, Krpa, Vidura, Gandhari and Drona. Showing sorrow equal to theirs, They cried out, “Alas, how painful this is!”
Purport:
Srila Sridhara Svami points out that those who were involved in the assassination attempt were of course not at all sorry to hear of the Pandavas’ death. The persons specifically mentioned here, however — Bhisma, Krpa, Vidura, Gandhari and Drona — were actually unhappy to hear of the supposed tragedy.
