6.5.30

nityaṃ śuklam ācchādanam apakṣudham annapānaṃ nityaṃ saugandhikena tāmbūlena ca yogaḥ sahiraṇyabhāgam alaṃkaraṇam iti kumbhadāsīnāṃ lābhātiśayaḥ//

Having a white dress to wear every day; getting sufficient food and drink to satisfy hunger and thirst; eating daily a perfumed tambula, i.e., a mixture of betel nut and betel leaves; and wearing ornaments gilt with gold. The Sages say that these represent the gains of all the middle and lower classes of courtezans, but Vatsyayana is of opinion that their gains cannot be calculated, or fixed in any way, as these depend on the influences of the place, the customs of the people, their own appearance, and many other things.
