Mahāsāṃghika in the context of "Luminous mind"

In Buddhism, an Arhat (Sanskrit: अर्हत्) or Arahant (Pali: अरहंत्, 𑀅𑀭𑀳𑀦𑁆𑀢𑁆) is one who has gained insight into the nature of existence, has achieved Nirvana, and has been liberated from the endless cycle of rebirth.

The understanding of the concept has changed over the centuries, and varies between different schools of Buddhism and different regions. A range of views on the attainment of arhats existed in the early Buddhist schools. The Sarvāstivāda, Kāśyapīya, Mahāsāṃghika, Ekavyāvahārika, Lokottaravāda, Bahuśrutīya, Prajñaptivāda, and Caitika schools all regarded arhats as imperfect in their attainments compared to buddhas.

Buddhism is an ancient Indian religion, which arose in and around the ancient Kingdom of Magadha (now Bihar, India). It is based on the teachings of Gautama Buddha, who lived in the 6th or 5th century BCE and was deemed a "Buddha" or an "Awakened One". Buddhist records in the Theravada tradition list Gautama Buddha as the fourth Buddha of our kalpa, while the next buddha will be Maitreya Buddha. Buddhism spread outside of Northern India beginning in the Buddha's lifetime.

In the 3rd century BCE and during the reign of the Mauryan Emperor Ashoka, the Buddhist community split into two schools: the Mahāsāṃghika and the Sthaviravāda, each of which spread throughout India and grew into numerous sub-schools. In modern times, three major branches of Buddhism exist: the Theravada in Sri Lanka and Southeast Asia, and the Mahayana in the Himalayas and East Asia, and the Vajrayana throughout Asia and specifically in Tibet, Nepal, and Bhutan.

The early Buddhist schools refers to the Indian Buddhist "doctrinal schools" or "schools of thought" (Sanskrit: vāda) which arose out of the early unified Buddhist monastic community (Saṅgha) due to various schisms in the history of Indian Buddhism. The various splits and divisions were caused by differences in interpretations of the monastic rule (Vinaya), doctrinal differences and also due to simple geographical separation as Buddhism spread throughout the Indian subcontinent.

The early Buddhist community initially split into two main Nikāyas (monastic groups, divisions): the Sthavira ("Elders"), and the Mahāsāṃghika ("Great Community"). This initial split occurred either during the reign of Aśoka (c. 268-232 BCE) or shortly after (historians disagree on the matter).

The Ekavyāvahārika (Sanskrit: एकव्यावहारिक; traditional Chinese: 一說部; ; pinyin: Yī Shuō Bù; Vietnamese: Nhất thuyết bộ) was one of the early Buddhist schools, and is thought to have separated from the Mahāsāṃghika sect during the reign of Aśoka.

The Lokottaravāda (Sanskrit: लोकोत्तरवाद; traditional Chinese: 說出世部; ; pinyin: Shuō Chūshì Bù; Vietnamese: Xuất thế thuyết bộ) was one of the early Buddhist schools according to Mahāyāna doxological sources compiled by Bhāviveka, Vinitadeva and others, and was a subgroup which emerged from the Mahāsāṃghika.

The Bahuśrutīya (Sanskrit: बहुश्रुतीय) was one of the early Buddhist schools, according to early sources such as Vasumitra, the Śāriputraparipṛcchā, and other sources, and was a sub-group which emerged from the Mahāsāṃghika sect.

The Prajñaptivāda (Sanskrit; traditional Chinese: 說假部; ; pinyin: Shuō Jiǎ Bù) was a branch of the Mahāsāṃghika, one of the early Buddhist schools in India. The Prajñaptivādins were also known as the Bahuśrutīya-Vibhajyavādins.

The Caitika (Chinese: 制多山部 or 制多部) was an early Buddhist school, a sub-sect of the Mahāsāṃghika. They were also known as the Caityaka sect.

The Caitikas proliferated throughout the mountains of South India, from which they derived their name. In Pali writings, members of this sect and its offshoots were generally referred to as the Andhakas, meaning "of Coastal Andhra".
