Celebrating the dead is not complete unless you visit the grave(s) of your loved one(s) to place flowers and candles. Cemeteries transform into parks with flowers and candles. This is quite something to experience.
The festivities are nowhere near the equivalent of the festive celebrations of the Day of the Dead in Mexico. However, it remains a spiritual time for families to get together and reflect.
It is believed that when a soul leaves the body, the soul is not completely clean from minor sins. However, through powerful prayers, the loved ones that were left behind on earth can help these souls the Beatific Vision they seek. And in doing so, bringing the soul eternal sublime happiness.
