"Various taxonomies of season, landscape, times, gunas or qualities (and their material bases), tastes, characters, emotions, essences (rasas), etc., are basic to the thought-work of Hindu medicine and poetry, cooking and religion, erotics and magic. Each jati or class defines a context, a structure of relevance, a rule of permissible combinations, a frame of reference, a meta-communication of what is and can be done … Even the Kama-Sutra is literally a grammar of love, which declines and conjugates men and women as one would nouns and verbs in different genders, voices, moods and aspects. Genders are genres. Different body-types and character-types obey different rules, respond to different scents and beckonings."
