For certain is death for the born, and certain is birth for the dead; therefore, over the inevitable thou shouldst not grieve.

For death is certain for whatever is born, and birth is certain for whatever dies. So you should not grieve over what cannot be avoided.

The reasoning is simple and universal. Death is certain for everything born, and birth is certain for whatever dies, within the round of becoming. What cannot be avoided is not a fitting object of grief. The verse does not deny the sorrow of loss; it asks Arjuna to see that his despair treats a natural law as a personal catastrophe. This point holds whether or not one accepts rebirth, which makes it a bridge between the metaphysical and the practical parts of Krishna's reply.
