No, all I have are reports of records. Something like that is probably what happened. I'm not sure if this represents an English or a Chinese mistake, though.
“If a bodhisattva resides as a householder and there appears a woman who is clearly unbound to anyone, habituated to sexual indulgence, attracted to the bodhisattva and seeking sexual activities, the bodhisattva having seen this thinks, 'Do not make her mind upset, producing much misfortune. If she pursues her desire, she will obtain freedom. As expedient means [upaya] I will take her in and have her plant the roots for virtue, also having her abandon unwholesome karma. I will engage in impure activities [abrahma-carya] with a compassionate mind.' Even practising such defiled activities like this, there is nothing that is violated [precepts], and much merit will be produced." -- from the Yogācārabhūmi Śāstra
