A BRAHMANA IS HE WHO IS DESIRELESS
Asa yassa na vijjanti asmim loke paramhi ca
Nirasayam visamyuttam tam aham brumi brahmanam.
He who has no desire either for this world or for the next, who is free from craving and from moral defilements, - him I call a brahmana. 
On one occasion, Venerable Sariputta accompanied by many other bhikkhus went to a monastery near a small village to spend thevassaperiod. On seeing Sariputta, the people promised to provide all the requisites for the bhikkhus. However at the end of thevassa, not all the requisites had been received. So Sariputta said, 'If people come to offer robes, send them to me. If they do not, please inform me also.' Then he left for the Jetavana monastery to see the Buddha. Other bhikkhus misunderstood Sariputta's instructions, and reported to the Buddha, 'Venerable Sir! Venerable Sariputta is still attached to material things like robes and other requisites of a bhikkhu.' The Buddha replied, 'Bhikkhus! Sariputta has no more craving. His intention in asking you to bring the robes to him is that, there will be no loss of merit to the lay disciples, and no loss of holy gain to the bhikkhus and samanera.'
