They told this thing to the Blessed One.

“I prescribe, O Bhikkhus, ten precepts for the novices, and the exercise of the novices in these (ten precepts), viz. abstinence from destroying life; abstinence from stealing; abstinence from impurity; abstinence from lying; abstinence from arrack and strong drink and intoxicating liquors, which cause indifference (to religion); abstinence from eating at forbidden times; abstinence from dancing, singing, music, and seeing spectacles; abstinence from garlands, scents, unguents, ornaments, and finery; abstinence from (the use of) high or broad beds; abstinence from accepting gold or silver. I prescribe, O Bhikkhus, these ten precepts for the novices, and the exercise of the novices in these (ten precepts).”
