2.118

"Let the saṃgha of elder sisters listen! The saṃgha now appoints Bhikṣuṇī N.N., for the sake of the saṃgha of bhikṣuṇīs, to go every half-month to the saṃgha of bhikṣus to seek instruction. Whichever elder sisters approve that 'the saṃgha appoints Bhikṣuṇī N.N., for the sake of the saṃgha of bhikṣuṇīs, to go every half-month to the saṃgha of bhikṣus to seek instruction,' remain silent; whoever does not approve, speak.
