2.118

【娑毘迦羅】亦云劫毘羅。此云金頭或云黃髮，食米臍外道。應法師云：「舊言食米屑也。外道修苦行，合手大指，及第三指，以物縛之。往至人家舂穀簸（補過）米處，以彼縛指，拾取米屑。聚至掌中，隨得多少，去以為食。若全粒者，即不取之。亦名䳕（音孚）鳩行，外道拾米，如䳕鳩行也。」

[Śavīkara] Also called Kapila. Rendered here as "Golden Head" or "Yellow Hair," the non-Buddhists who eat rice germ. Master Ying says: "The older rendering was 'eating rice fragments.' These non-Buddhists practiced austerities: they tied together the thumb and the third finger of the hand with an object, went to houses where grain was being pounded and rice winnowed, and with those bound fingers gathered up rice fragments. Gathering them in the palm, whatever amount they obtained, they took away to eat. If they were whole grains, they would not take them. It is also called the 'turtle-dove practice,' for non-Buddhists picking up rice resemble the walking of turtle-doves."
