The Arahant Knows
The arahant knows with certainty that his mind is devoid of defilements. He has penetrated the Four Noble Truths. He becomes neither despondent nor elated through contact with the eight worldly conditions — gain and loss, honor and dishonor, happiness and misery, praise and blame.
He is free from sorrow, stainless, and safe. “Free from sorrow” because he no more weeps and laments; “stainless” because he has no more defilements; “safe” because there is no more birth for him.
