The Buddha went on his way, modestly and deep in his thoughts, his calm face was neither happy nor sad, it seemed to smile quietly and inwardly. With a hidden smile, quiet, calm, somewhat resembling a healthy child, the Buddha walked, wore the robe and placed his feet just as all of his monks did, according to a precise rule. But his face and his walk, his quietly lowered glance, his quietly dangling hand and even every finger of his quietly dangling hand expressed peace, expressed perfection, did not search, did not imitate, breathed softly in an unwhithering calm, in an unwhithering light, an untouchable peace.
Thus Gotama walked towards the town, to collect alms, and the two Samanas recognized him solely by the perfection of his calm, by the quietness of his appearance, in which there was no searching, no desire, no imitation, no effort to be seen, only light and peace. (3.12-13)
