"A true buddhist is the happiest of beings. He has no fears or anxieties. He is always calm and serene, and cannot be upset or dismayed by changes or calamities, because he sees things as they are.

Although there is suffering in life, a buddhist should not be gloomy over it, should not be angry or impatient at it.

Being impatient or angry at suffering does not remove it."

What the Buddha taught - p.28
