Commentary: Already slain by Me Therefore, O Arjuna, you need not be afraid of incurring sin by killing them.Drona had celestial weapons. He was Arjunas teacher in the science of archery. He was Arjunas beloved and greatest Guru. Bhishma also possessed celetial weapons. He could die only if and when he wanted to die. He once faught singlehanded with Lord Parasurama and was not defeated. So powerful was he.The father of Jayadratha performed penance with a resolve the head of the man who may cause the head of my son to fall on the ground, shall also fall.
