The soul is spoken of as invisible, inconceivable, and unchangeable. Knowing this, you should not grieve for the body.

The Bhagavad Gita

Knowing This

Topic: Life Beyond Death & the Spirit World

Weapons cannot shred the soul, nor can fire burn it. Water cannot wet it, nor can the wind dry it. The soul is unbreakable and incombustible; it can neither be dampened nor dried. It is everlasting, in all places, unalterable, immutable, and primordial. The soul is spoken of as invisible, inconceivable, and unchangeable. Knowing this, you should not grieve for the body.
