This term denotes the two accumulations of merit and wisdom that are gathered by bodhisattvas on the path to buddhahood.

In Buddhist literature, this is an epithet applied to buddhas, most often to Śākyamuni. The Sanskrit term generally means “possessing fortune,” but in specifically Buddhist contexts it implies that a buddha is in possession of six auspicious qualities (bhaga) associated with complete awakening. The Tibetan term‍—where bcom is said to refer to “subduing” the four māras, ldan to “possessing” the great qualities of buddhahood, and ’das to “going beyond” saṃsāra and nirvāṇa‍—possibly reflects the commentarial tradition where the Sanskrit bhagavat is interpreted, in addition, as “one who destroys the four māras.” This is achieved either by reading bhagavat as bhagnavat (“one who broke”), or by tracing the word bhaga to the root √bhañj (“to break”).

A being who is dedicated to the cultivation and fulfilment of the altruistic intention to attain perfect buddhahood, traversing the ten bodhisattva levels (daśabhūmi, sa bcu). Bodhisattvas purposely opt to remain within cyclic existence in order to liberate all sentient beings, instead of simply seeking personal freedom from suffering. In terms of the view, they realize both the selflessness of persons and the selflessness of phenomena.

This term denotes the operational field of a specific buddha, spontaneously arising as a result of his altruistic aspirations.

The essentially pure nature of mind is obscured and afflicted by various psychological defilements, which destroy the mind’s peace and composure and lead to unwholesome deeds of body, speech, and mind, acting as causes for continued existence in saṃsāra. Included among them are the primary afflictions of desire (rāga), anger (dveṣa), and ignorance (avidyā). It is said that there are eighty-four thousand of these negative mental qualities, for which the eighty-four thousand categories of the Buddha’s teachings serve as the antidote.

Kleśa is also commonly translated as “negative emotions,” “disturbing emotions,” and so on. The Pāli kilesa, Middle Indic kileśa, and Buddhist Hybrid Sanskrit kleśa all primarily mean “stain” or “defilement.” The translation “affliction” is a secondary development that derives from the more general (non-Buddhist) classical understanding of √kliś (“to harm,“ “to afflict”). Both meanings are noted by Buddhist commentators.

Morally virtuous or disciplined conduct and the abandonment of morally undisciplined conduct of body, speech, and mind. In a general sense, moral discipline is the cause for rebirth in higher, more favorable states, but it is also foundational to Buddhist practice as one of the three trainings (triśikṣā) and one of the six perfections of a bodhisattva. Often rendered as “ethics,” “discipline,” and “morality.”

According to traditional Buddhist cosmology, our universe consists of a central mountain, known as Mount Meru or Sumeru, surrounded by four island continents (dvīpa), one in each of the four cardinal directions. The Abhidharmakośa explains that each of these island continents has a specific shape and is flanked by two smaller subcontinents of similar shape. To the south of Mount Meru is Jambudvīpa, corresponding either to the Indian subcontinent itself or to the known world. It is triangular in shape, and at its center is the place where the buddhas attain awakening. The humans who inhabit Jambudvīpa have a lifespan of one hundred years. To the east is Videha, a semicircular continent inhabited by humans who have a lifespan of two hundred fifty years and are twice as tall as the humans who inhabit Jambudvīpa. To the north is Uttarakuru, a square continent whose inhabitants have a lifespan of a thousand years. To the west is Godānīya, circular in shape, where the lifespan is five hundred years.

Either birth, old age, sickness, and death, or desire (’dod pa), existence (srid pa), ignorance (ma rig pa), and wrong views (log par lta ba).

This term denotes the ontological status of phenomena, according to which they are attributed with existence in their own right, inherently, in and of themselves, objectively, and independent of any other phenomena such as our conception and labeling. The absence of such an ontological reality is defined as the true nature of reality, emptiness.

An important form of Buddhist meditation focusing on developing insight into the nature of phenomena. Often presented as part of a pair of meditation techniques, the other being śamatha, “calm abiding”.

An ancient Indian kingdom that lay to the south of the Ganges River in what today is the state of Bihar. Magadha was the largest of the sixteen “great states” (mahājanapada) that flourished between the sixth and third centuries ʙᴄᴇ in northern India. During the life of the Buddha Śākyamuni, it was ruled by King Bimbisāra and later by Bimbisāra's son, Ajātaśatru. Its capital was initially Rājagṛha (modern-day Rajgir) but was later moved to Pāṭaliputra (modern-day Patna). Over the centuries, with the expansion of the Magadha’s might, it became the capital of the vast Mauryan empire and seat of the great King Aśoka.

This region is home to many of the most important Buddhist sites, including Bodh Gayā, where the Buddha attained awakening; Vulture Peak (Gṛdhra­kūṭa), where the Buddha bestowed many well-known Mahāyāna sūtras; and the Buddhist university of Nālandā that flourished between the fifth and twelfth centuries ᴄᴇ, among many others.

Dhyāna is defined as one-pointed abiding in an undistracted state of mind, free from afflicted mental states. Four states of dhyāna are identified as being conducive to birth within the form realm. In the context of the Mahāyāna, it is the fifth of the six perfections. It is commonly translated as “concentration,” “meditative concentration,” and so on.

In a general sense, samādhi can describe a number of different meditative states. In the Mahāyāna literature, in particular in the Prajñāpāramitā sūtras, we find extensive lists of different samādhis, numbering over one hundred.

In a more restricted sense, and when understood as a mental state, samādhi is defined as the one-pointedness of the mind (cittaikāgratā), the ability to remain on the same object over long periods of time. The Drajor Bamponyipa (sgra sbyor bam po gnyis pa) commentary on the Mahāvyutpatti explains the term samādhi as referring to the instrument through which mind and mental states “get collected,” i.e., it is by the force of samādhi that the continuum of mind and mental states becomes collected on a single point of reference without getting distracted.

This is the faculty that enables the mind to maintain its attention on a referent object, counteracting the arising of forgetfulness, which is a great obstacle to meditative stability. The root smṛ may mean “to recollect” but also simply “to think of.” Broadly speaking, smṛti, commonly translated as “mindfulness,” means to bring something to mind, not necessarily something experienced in a distant past but also something that is experienced in the present, such as the position of one’s body or the breath.

Together with alertness (samprajāna, shes bzhin), it is one of the two indispensable factors for the development of calm abiding (śamatha, zhi gnas).

The obscurations to liberation and omniscience. They are generally categorized as two types: affective obscurations (kleśāvaraṇa), the arising of afflictive emotions; and cognitive obscurations (jñeyāvaraṇa), those caused by misapprehension and incorrect understanding about the nature of reality.

The term is used also as a reference to a set five hindrances on the path: longing for sense pleasures (Skt. kāmacchanda), malice (Skt. vyāpāda), sloth and torpor (Skt. styānamiddha), excitement and remorse (Skt. auddhatyakaukṛtya), and doubt (Skt. vicikitsā).

The real nature, true quality, or condition of things. Throughout Buddhist discourse this term is used in two distinct ways. In one, it designates the relative nature that is either the essential characteristic of a specific phenomenon, such as the heat of fire and the moisture of water, or the defining feature of a specific term or category. The other very important and widespread way it is used is to designate the ultimate nature of all phenomena, which cannot be conveyed in conceptual, dualistic terms and is often synonymous with emptiness or the absence of intrinsic existence.

The concept of skillful means is central to the understanding of the Buddha’s enlightened deeds and the many scriptures that are revealed contingent to the needs, interests, and mental dispositions of specific types of individuals. According to the Great Vehicle, training in skillful means collectively denotes the first five of the six perfections when integrated with wisdom, the sixth perfection, to form a union of wisdom and means.

The bodhisattva who is the primary interlocutor in this text.

A frequently used synonym for buddha. According to different explanations, it can be read as tathā-gata, literally meaning “one who has thus gone,” or as tathā-āgata, “one who has thus come.” Gata, though literally meaning “gone,” is a past passive participle used to describe a state or condition of existence. Tatha­(tā), often rendered as “suchness” or “thusness,” is the quality or condition of things as they really are, which cannot be conveyed in conceptual, dualistic terms. Therefore, this epithet is interpreted in different ways, but in general it implies one who has departed in the wake of the buddhas of the past, or one who has manifested the supreme awakening dependent on the reality that does not abide in the two extremes of existence and quiescence. It is also often used as a specific epithet of the Buddha Śākyamuni.

Literally, “to flow” or “to ooze.” Mental defilements or contaminations that “flow out” toward the objects of cyclic existence, binding us to them.

This term has three meanings: (1) the ultimate nature, (2) the experience of the ultimate nature, and (3) the quiescent state of a worthy one (arhat) to be avoided by bodhisattvas.
