Sum quod eris, fui quod es

“Sum quod eris, fui quod es” is a Latin phrase that means “I am what you will be, I was what you are” in English. This phrase portrays the idea that life is transient and death is inevitable. It suggests that the speaker or subject has gone through what the listener or subject will experience in the future and vice versa. It is often used to reflect on the shared human experience of birth, life, and death and the cyclical nature of life.
