Prajnaparamita means "the Perfection of Transcendent Wisdom" in Mahayana Buddhism. Prajnaparamita refers to this perfected way of seeing the nature of reality, as well as to a particular body of sutras and the embodiment of the concept in the Bodhisattva known as the "Great Mother" (Tibetan: Yum Chenmo). The word Prajnaparamita combines the Sanskrit words prajna "wisdom" with paramita "perfection". Prajnaparamita is a central concept in Mahayana Buddhism and is generally associated with the doctrine of emptiness (Shunyata) or 'lack of Svabhava' (essence). Its practice and understanding are taken to be an essential part of the path of the Bodhisattva.

Astasahasrika Pajanaparmita
Earliest Prajnaparamita Sutra is Astasahasrika Pajanaparmita Sutra, which was probably put in writing in the 1st century BCE. The first translation of the Astasahasrika Prajnaparamita also has a corresponding version in poetry format called the Ratnagu?asamcaya Gatha, which some believe to be slightly older because it is not written in Sanskrit. However, these findings rely on late-dating Indian texts, in which poetry and mantras are often kept in archive forms.

Mahayana Prajnaparamita teachings were first developed by the Caitika subsect of the Mahasamghikas. Astasahasrika Prajnaparamita Sutra originated amongst Mahasamghika schools and they had two copy of the Astasahasrika Prajnaparamita Sutra in Prakrit Script.

In 2012, A partially damaged, Kharosthi manuscript of the Astasahasrika Prajnaparamita was radiocarbon dated to 75 CE , making it one of the oldest Buddhist texts in existence.
