The 12 forests of Vraja bring us 12 spiritual tastes

“Srila Bhaktisiddhanta Sarasvati Thakura states that the business of the tongue is to gratify itself with the varieties of flavor, but by wandering in the twelve holy forests of Vraja-mandala (Vrndavana), one can be freed from the twelve flavors of material sense gratification. The five principal divisions of material relationships are neutral admiration, servitude, friendship, parental affection and conjugal love; the seven subordinate features of material relationships are material humor, astonishment, chivalry, compassion, anger, dread and ghastliness. Originally, these twelve rasas, or flavors of relationships, are exchanged between the Supreme Personality of Godhead and the living entity in the spiritual world; and by wandering in the twelve forests of Vrndavana one can re-spiritualize the twelve flavors of personal existence. Thus one will become a liberated soul, free from all material desires.”
