In Vedic philosophy, sattva (Sanskrit sattva / "purity", literally "existence, reality"; adjectival sāttvika "pure", anglicised sattvic) is the most rarefied of the three gunas in Samkhya, sāttvika "pure", rājasika "excitable", and tāmasika "indifferent". Importantly, no value judgement is entailed as all guna are indivisible and mutually qualifying.
