For him who has completed the journey, for him who is sorrowless, for him who from everything is wholly free, for him who has destroyed all ties, the fever of passion exists not. He whose corruptions are destroyed, he who is not attached to food, he who has deliverance, which is void [of lust, hate, and ignorance] and signless [without the signs of lust, etc.], as his object--his path, like that of the birds of the air, cannot be traced. He whose senses are subdued, like steeds well-trained by a charioteer, he whose pride is destroyed and is free from the corruptions--such a steadfast one even the gods hold dear. Like the earth, a balanced and well-disciplined person resents not.... He is like a pool, unsullied by mud; to such a balanced one, life's wanderings do not arise. Calm is his mind, calm is his speech, calm is his action, who, rightly knowing, is wholly freed [from defilements], perfectly peaceful and equipoised. The man who is not credulous but truly understands the Uncreated (Nibbana), who has cut off the links, who has put an end to occasion [of good and evil], who has eschewed all desires, he indeed is a supreme man.

(Buddha Sakyamuni)
