lokād evākṛtapratyayād aguṇo guṇavān vety anavekṣya gamanaṃ kāmo dveṣa iti saṃśayaḥ/

(c) If a courtezan relies solely upon the report of other people (i.e., hearsay) about a man, and goes to him without ascertaining herself whether he possesses good qualities or not, she may either gain or lose pleasure in proportion as he may be good or bad, and therefore this is called a mixed doubt about the gain and loss of pleasure.
