Swami Mukundananda
Why does the death of a loved one hurt so much?
Grief comes from attachment
The mind is always hankering for material things and attaches itself to father, mother, husband, wife, sister, brother, so separation brings pain. Since everyone must go one day, the saints advise not attaching the mind anywhere.
That is why, when somebody passes away, we lament. But why lament? You know everybody has to go one day, and that all this is temporary.
