Buddhist philosophy in the context of "Buddhist paths to liberation"

Eastern philosophy (also called Asian philosophy or Oriental philosophy) includes the various philosophies that originated in East and South Asia, including Chinese philosophy, Japanese philosophy, Korean philosophy, and Vietnamese philosophy, which are dominant in East Asia; and Indian philosophy (including Hindu philosophy, Jain philosophy, Buddhist philosophy), which are dominant in South Asia, Southeast Asia, Tibet, Japan and Mongolia.

Philosophy of self examines the idea of the self at a conceptual level. Many different ideas on what constitutes self have been proposed, including the self being an activity, the self being independent of the senses, the bundle theory of the self, the self as a narrative center of gravity, and the self as a linguistic or social construct rather than a physical entity. The self (or its non-existence) is also an important concept in Eastern philosophy, including Buddhist philosophy.

Dualism in Indian philosophy is a belief, or large spectrum of beliefs, held by certain schools of Indian philosophy that reality is fundamentally composed of two parts or two types of existence. This mainly takes the form of either mind-matter dualism, as in some strands of Buddhist philosophy, or consciousness-nonconsciousness dualism in the Samkhya and Yoga schools of Hindu philosophy. These can be compared and contrasted with mind-body dualism in Western philosophy of mind and metaphysics.

Another form of dualism in Hindu philosophy is found in the Dvaita ("dualism") Vedanta school, which regards God and the world as two realities with distinct essences; this is a form of theistic dualism. By contrast, schools such as Advaita ("nondualism") Vedanta embrace nondualism or absolute monism, regarding dualism as an illusion (maya).

The schools of Buddhism are the various institutional and doctrinal divisions of Buddhism, which have often been based on historical sectarianism and the differing teachings and interpretations of specific Buddhist texts. The branching of Buddhism into separate schools has been occurring from ancient times up to the present. The classification and nature of the various doctrinal, philosophical or cultural facets of the schools of Buddhism is vague and has been interpreted in many different ways, often due to the sheer number (perhaps thousands) of different sects, sub-sects, movements, etc. that have made up or currently make up the whole of the Buddhist tradition. The sectarian and conceptual divisions of Buddhist thought are part of the modern framework of Buddhist studies, as well as comparative religion in Asia. Some factors in Buddhist doctrine appear to be consistent across different schools, such as the afterlife and the Buddha, while others vary considerably.

From a largely English-language standpoint, and to some extent in most of Western academia, Buddhism is separated into two groups: Theravāda (lit. 'the Teaching of the Elders' or 'the Ancient Teaching'), and Mahāyāna (lit. 'the Great Vehicle'). The most common classification among scholars is threefold: Theravāda, Mahāyāna and Vajrayāna.

Mahayana is the largest branch of Buddhism, followed by Theravada. It is a broad group of Buddhist traditions, texts, philosophies, and practices developed in ancient India (c. 1st century BCE onwards). Mahāyāna accepts the main scriptures and teachings of early Buddhism but also recognizes various doctrines and texts that are not accepted by Theravada Buddhism as original. These include the Mahāyāna sūtras and their emphasis on the bodhisattva path and Prajñāpāramitā. Vajrayana or Mantra traditions are a subset of Mahāyāna which makes use of numerous Tantric methods Vajrayānists consider to help achieve Buddhahood.

Mahāyāna also refers to the path of the bodhisattva striving to become a fully awakened Buddha for the benefit of all sentient beings, and is thus also called the "Bodhisattva Vehicle" (Bodhisattvayāna). Mahāyāna Buddhism generally sees the goal of becoming a Buddha through the bodhisattva path as being available to all and sees the state of the arhat as incomplete. Mahāyāna also includes numerous Buddhas and bodhisattvas that are not found in Theravada (such as Amitābha and Vairocana). Mahāyāna Buddhist philosophy also promotes unique theories, such as the Madhyamaka theory of emptiness (śūnyatā), the Vijñānavāda ("the doctrine of consciousness" also called "mind-only"), and the Buddha-nature teaching.

The Aṣṭasāhasrikā Prajñāpāramitā Sūtra (Sanskrit: अष्टसाहस्रिका प्रज्ञापारमिता सूत्र; English: The Perfection of Wisdom in Eight Thousand [Lines]) is a Mahāyāna Buddhist sūtra in the category of Prajñāpāramitā sūtra literature. The sūtra's manuscript witnesses date to at least c. 184 BCE – c. 46 BCE, making it among the oldest Buddhist manuscripts in existence. The sūtra forms the basis for the expansion and development of the Prajñāpāramitā sūtra literature. In terms of its influence in the development of Buddhist philosophical thought, P.L. Vaidya writes that "all Buddhist writers from Nāgārjuna, Āryadeva, Maitreyanātha, Asaṅga, Vasubandhu, Dignāga, down to Haribhadra concentrated their energies in interpreting Aṣṭasāhasrikā only," making it of great significance in the development of Madhyāmaka and Yogācāra thought.

The sūtra deals with a number of topics, but is primarily concerned with the conduct of a bodhisattva, the realisation and attainment of the Perfection of Wisdom as one of the Six Perfections, the realisation of thusness (tathātā), the attainment of irreversibility on the path to buddhahood (avaivartika), non-conceptualisation and abandonment of views, as well as the worldly and spiritual benefit of worshipping the sūtra.

The Constitution of the Kingdom of Bhutan (Dzongkha: འབྲུག་གི་རྩ་ཁྲིམས་ཆེན་མོ་; Wylie: 'Druk-gi tsa-thrims-chen-mo) was enacted 18 July 2008 by the Royal Government of Bhutan. The Constitution was thoroughly planned by several government officers and agencies over a period of almost seven years amid increasing democratic reforms in Bhutan. The current Constitution is based on Buddhist philosophy, international Conventions on Human Rights, comparative analysis of 20 other modern constitutions, public opinion, and existing laws, authorities, and precedents. According to Princess Sonam Wangchuck, the constitutional committee was particularly influenced by the Constitution of South Africa because of its strong protection of human rights.

Mindstream (Pali: citta-santāna, Sanskrit: citta-saṃtāna, Tibetan: sems-rgyud, Ch: xin xiangxu 心相續) in Buddhist philosophy is the moment-to-moment continuum of sense impressions and mental phenomena (citta), which is also described as continuing from one life to another. Often described as a "stream of mind" or "mental continuum," the mindstream is not a static entity but a dynamic flow of arising and passing mental phenomena, which refers as a string of passing moments that happen either in the same lifetime or in the transitional period between one life and another.
