Kanishka in the context of "Indo-Scythians"

Aśvaghoṣa, also transliterated Ashvaghosha (Sanskrit: [ˌɐɕʋɐˈɡʱoːʂɐ], अश्वघोष; lit. "Having a Horse-Voice"; Tibetan: སློབ་དཔོན་དཔའ་བོ།, Wylie: slob dpon dpa' bo; Chinese: 馬鳴菩薩; pinyin: Mǎmíng púsà; lit. 'Bodhisattva with a Horse-Voice') (c. 80 – c. 150 CE), was a Buddhist philosopher, dramatist, poet, musician, and orator from India. He was born in Saketa, today known as Ayodhya.

He is believed to have been the first Sanskrit dramatist, and is considered the greatest Indian poet prior to Kālidāsa. It seems probable that he was the contemporary and spiritual adviser of Kanishka in the first century of our era. He was the most famous in a group of Buddhist court writers, whose epics rivaled the contemporary Ramayana. Whereas much of Buddhist literature prior to the time of Aśvaghoṣa had been composed in Pāli and Prakrit, Aśvaghoṣa wrote in Classical Sanskrit. He may have been associated with the Sarvāstivāda or the Mahasanghika schools.

Mahayana Buddhism entered Han China via the Silk Road, beginning in the 1st or 2nd century CE. The first documented translation efforts by Buddhist monks in China were in the 2nd century CE via the Kushan Empire into the Chinese territory bordering the Tarim Basin under Kanishka. These contacts transmitted strands of Sarvastivadan and Tamrashatiya Buddhism throughout the Eastern world.

Theravada Buddhism developed from the Pāli Canon in Sri Lanka Tamrashatiya school and spread throughout Southeast Asia. Meanwhile, Sarvastivada Buddhism was transmitted from North India through Central Asia to China. Direct contact between Central Asian and Chinese Buddhism continued throughout the 3rd to 7th centuries, much into the Tang period. From the 4th century onward, Chinese pilgrims like Faxian (395–414) and later Xuanzang (629–644) started to travel to northern India in order to get improved access to original scriptures. Between the 3rd and 7th centuries, parts of the land route connecting northern India with China was ruled by the Xiongnu, Han dynasty, Kushan Empire, the Hephthalite Empire, the Göktürks, and the Tang dynasty. The Indian form of Buddhist tantra (Vajrayana) reached China in the 7th century. Tibetan Buddhism was likewise established as a branch of Vajrayana, in the 8th century.

Kujula Kadphises (Kushan language: Κοζουλου Καδφιζου, also Κοζολα Καδαφες; Kharosthi: 𐨐𐨂𐨗𐨂𐨫 𐨐𐨯, IAST: Ku-ju-la Ka-sa, Kujula Kasa; Chinese: 丘就卻; pinyin: Qiūjiùquè; r. 30–80 CE, or 40–90 CE according to Bopearachchi. 25–85 CE as per Benjamin.) was a Kushan prince who united the Yuezhi confederation in Bactria during the 1st century CE, and became the first Kushan emperor. According to the Rabatak inscription, he was the great grandfather of Kanishka I. He is considered the founder of the Kushan Empire.

Vima Kadphises (Greek: Οοημο Καδφιϲηϲ Ooēmo Kadphisēs (epigraphic); Kharosthi: 𐨬𐨁𐨨 𐨐𐨫𐨿𐨤𐨁𐨭 Vi-ma Ka-lpi-śa, Vima Kalpiśa) was a Kushan emperor from approximately 113 to 127 CE. According to the Rabatak inscription, he was the son of Vima Takto and the father of Kanishka.

The Sarvāstivāda (Sanskrit: 𑀲𑀭𑁆𑀯𑀸𑀲𑁆𑀢𑀺𑀯𑀸𑀤; Pali: 𑀲𑀩𑁆𑀩𑀢𑁆𑀣𑀺𑀯𑀸𑀤, romanized: Sabbatthivāda Chinese: 說一切有部; pinyin: Shuōyīqièyǒu Bù; Japanese: せついっさいうぶ; Korean: 설일체유부; Vietnamese: Nhất thiết hữu bộ; Thai: สรวาสติวาท; Sinhala: සර්වාස්තිවාද) was one of the early Buddhist schools established around the reign of Ashoka (third century BCE). It was particularly known as an Abhidharma tradition, with a unique set of seven canonical Abhidharma texts.

The Sarvāstivādins were one of the most influential Buddhist monastic groups, flourishing throughout North India, especially Kashmir and Central Asia, until the 7th century CE. The orthodox Kashmiri branch of the school composed the large and encyclopedic Abhidharma Mahāvibhāṣa Śāstra around the time of the reign of Kanishka (c. 127–150 CE). Because of this, orthodox Sarvāstivādins who upheld the doctrines in the Mahāvibhāṣa were called Vaibhāṣikas.

The Rabatak Inscription is a stone inscribed with text written in the Bactrian language and Greek script, found in 1993 at Rabatak, near Surkh Kotal in Afghanistan. The inscription relates to the rule of the Kushan emperor Kanishka, and gives remarkable clues on the genealogy of the Kushan dynasty. It dates to the 2nd century CE.
