The Blessed Lord says:

Though you hold learned discourses, you grieve without reason. Neither the living nor the dead do the wise man mourn.

Never was the time when we did not exist, I, you and all these kings; and never did any of us cease to be.

At the moment of death, the soul takes on a new body, as naturally as it passed, in the previous one, from childhood to youth, then to old age. This change does not disturb those who are aware of their spiritual nature.

Ephemeral joys and sorrows, like summers and winters, come and go. They are only due to the encounter of the senses with matter, and one must learn to tolerate them, without being affected by them.

He who is unaffected by joys and sorrows, who remains serene and resolute in all circumstances, is worthy of liberation.

The masters of truth have concluded that the real is eternal and the illusory is impermanent, and this after studying their respective nature.

Know that that which penetrates the whole body cannot be destroyed. No one can destroy the imperishable soul.

The soul is indestructible, eternal and without measure; only the material bodies it borrows are subject to destruction. With this knowledge, engage in battle.

Ignorant is he who believes that the soul can kill or be killed; the wise man knows that it neither kills nor dies.

The soul knows neither birth nor death. It is alive and will never cease to be. Unborn, immortal, original, eternal, it has never had a beginning and will never have an end. It does not die with the body.

How can he who knows that the soul is unborn, immutable, eternal and indestructible, kill or cause to be killed?

At the moment of death, the soul puts on a new body, the old one no longer needed, just as one puts on new clothes when one has worn them out.

No weapon can split the soul, nor fire burn it; water cannot wet it, nor wind dry it.

The soul is indivisible and insoluble; fire does not reach it, it cannot be dried up. It is immortal and eternal, omnipresent, unalterable and fixed.

It is said of the soul that it is invisible, inconceivable and immutable. Knowing this, you should not lament over the body.

And even if you believe the soul to be endlessly taken up by birth and death, you have no reason to grieve.

Death is certain for him who is born, and birth is certain for him who dies. Since you must do your duty, you should not grieve in this way.
