Besides emptiness, Mahayana schools often place emphasis on the notions of perfected spiritual insight (prajnaparamita) and Buddha-nature (tathagatagarbha). There are conflicting interpretations of the tathagatagarbha in Mahayana thought. The idea may be traced to Abhidharma, and ultimately to statements of the Buddha in the Nikayas. In Tibetan Buddhism, according to the Sakya school, tathagatagarbha is the inseparability of the clarity and emptiness of one's mind. In Nyingma, tathagatagarbha also generally refers to inseparability of the clarity and emptiness of one's mind. According to the Gelug school, it is the potential for sentient beings to awaken since they are empty (i.e. dependently originated). According to the Jonang school, it refers to the innate qualities of the mind that expresses themselves as omniscience etc. when adventitious obscurations are removed. The "Tathagatagarbha Sutras" are a collection of Mahayana sutras that present a unique model of Buddha-nature. Even though this collection was generally ignored in India, East Asian Buddhism provides some significance to these texts.
According to what school is tathgatagarbha the inseparability of clairty and emptiness of one's mind?

The classical period of Greek civilization covers a time spanning from the early 5th century BC to the death of Alexander the Great, in 323 BC (some authors prefer to split this period into 'Classical', from the end of the Persian wars to the end of the Peloponnesian War, and 'Fourth Century', up to the death of Alexander). It is so named because it set the standards by which Greek civilization would be judged in later eras. The Classical period is also described as the "Golden Age" of Greek civilization, and its art, philosophy, architecture and literature would be instrumental in the formation and development of Western culture.

According to R. J. Rummel, genocide has 3 different meanings. The ordinary meaning is murder by government of people due to their national, ethnic, racial, or religious group membership. The legal meaning of genocide refers to the international treaty, the Convention on the Prevention and Punishment of the Crime of Genocide. This also includes non-killings that in the end eliminate the group, such as preventing births or forcibly transferring children out of the group to another group. A generalized meaning of genocide is similar to the ordinary meaning but also includes government killings of political opponents or otherwise intentional murder. It is to avoid confusion regarding what meaning is intended that Rummel created the term democide for the third meaning.
The legal meaning of genocide is contained in which international treaty?
