Swami Mukundananda
How can I overcome grief after losing a loved one?
Bring knowledge and detachment to your grief
After the period of grieving, decide that continuing in grief is your own weakness and attachment, and bring knowledge to yourself: everyone has to go one day. Seek God, your eternal relative.
Everybody had to go one day. When the Sun sets we don't grieve, we know that it rose and it will set.
