Shanta Rasa
Śāntarasa (Sanskrit: शान्तरस, occasionally spelled shantarasa, santarasa; transl. the imaginative experience of tranquility, emotion of emotionlessness) is considered as a ninth rasa, a concept of aesthetic flavour in Sanskrit literature. According to translation of Abhinavabhārati, Abhinavagupta's commentary on Nāṭyaśāstra by some experts, śāntarasa may be defined as: "that which brings happiness and welfare to all beings and which is accompanied by the stabilization (saṃsthitā) in the Self". It has as its stable emotion (sthāyibhāva) as impassivity (sama) which culminates in detachment (Vairāgya) arising from knowledge of truth and purity of mind. According to J L Masson and M V Patwardhan, who have collected the original manuscripts and translated Abhinavagupta's work, observe: the audience undergoes  transcendental experience, which is basic to all aesthetic experience in a play based on śāntarasa.
