There is a way to be purified, to overcome sorrows and grief, to release suffering, to secure the right path to realize nirvana. This is to be mindful.
What is the noble truth of suffering? Birth is suffering, ageing is suffering and sorrow and lamentation, pain, grief and despair are suffering.
From craving is born grief, from craving is born fear. For one freed from craving there's no grief- so how fear?
There are friendships to one who lives in society; thus our present grief arises from having friendships; observing the evils resulting from friendship, let one walk alone like a rhinoceros.
