According to the Yanomamö Indians, you should. Deep in the rainforests of southern Venezuela and northwestern Brazil, the Yanomamö people have real concerns about holding on to their souls. Maintaining possession of their soul is such a worry they won’t reveal their true names to strangers, as they fear they might lose their soul as a result.
But the Yanomamö soul protection practices don’t stop there. Their religious beliefs center around the care and keeping of the soul. When a member of their family group dies, it is left to the surviving members to ensure the soul of the deceased is protected from loss or intervention by evil forces. They cremate the body and eat the ashes to protect the soul. This so serious to them because they believe they can lose their souls if this isn’t done correctly. When they are at war with other tribes or etc. they threaten them by saying they aren’t going to eat their ashes.
This shows extreme loyalty and dedication to the dead from their loved ones.
