Taṇhā in the context of "Pāli"

Upādāna (Hindi: उपादान) is a Sanskrit and Pali word that means "fuel, material cause, substrate that is the source and means for keeping an active process energized". It is also an important Buddhist concept referring to "attachment, clinging, grasping". It is considered to be the result of taṇhā (craving), and is part of the duhkha (dissatisfaction, suffering, pain) doctrine in Buddhism.

In Buddhism, the Four Noble Truths (Sanskrit: चत्वार्यार्यसत्यान, romanized: catvāryāryasatyāni; Pali: cattāri ariyasaccāni; "The Four arya satya") are "the truths of the noble one (the Buddha)," a statement of how things really are when they are seen correctly. The four truths are

• dukkha (not being at ease, 'suffering', from dush-stha, standing unstable). Dukkha is an innate characteristic of transient existence; nothing is forever, this is painful;
• samudaya (origin, arising, combination; 'cause'): together with this transient world and its pain, there is also thirst (desire, longing, craving) for and attachment to this transient, unsatisfactory existence;
• nirodha (cessation, ending, confinement): the attachment to this transient world and its pain can be severed or contained by the confinement or letting go of this craving;
• marga (road, path, way): the Noble Eightfold Path is the path leading to the confinement of this desire and attachment, and the release from dukkha.

The four truths appear in many grammatical forms in the ancient Buddhist texts, and are traditionally identified as the first teaching given by the Buddha. While often called one of the most important teachings in Buddhism, they have both a symbolic and a propositional function. Symbolically, they represent the awakening and liberation of the Buddha, and of the potential for his followers to reach the same liberation and freedom that he did. As propositions, the Four Truths are a conceptual framework that appear in the Pali canon and early Hybrid Sanskrit Buddhist scriptures, as a part of the broader "network of teachings" (the "dhamma matrix"), which have to be taken together. They provide a conceptual framework for introducing and explaining Buddhist thought, which has to be personally understood or "experienced".

Vajrayāna (Sanskrit: वज्रयान, lit. 'Diamond Vehicle or Thunderbolt Vehicle'), otherwise known as Mantrayāna ("Mantra Vehicle"), Guhyamantrayāna ("Secret Mantra Vehicle"), Tantrayāna ("Tantra Vehicle"), Indo-Tibetan Buddhism, Tantric Buddhism, and Esoteric Buddhism, is a Mahāyāna Buddhist tradition that emphasizes esoteric practices and rituals aimed at rapid spiritual awakening. Emerging between the 5th and 7th centuries CE in medieval India, Vajrayāna Buddhism incorporates a range of techniques, including the use of mantras (sacred sounds), dhāraṇīs (mnemonic codes), mudrās (symbolic hand gestures), mandalās (spiritual diagrams), and the visualization of deities and Buddhas. These practices are designed to transform ordinary experiences into spiritual paths toward enlightenment and liberation, often by engaging with aspects of desire and aversion in a ritualized context.

A distinctive feature of Vajrayāna Buddhism is its emphasis on esoteric transmission, where teachings are passed directly from teacher (guru or vajrācārya) to student through initiation ceremonies. Tradition asserts that these teachings have been passed down through an unbroken lineage going back to the historical Buddha (c. the 5th century BCE), sometimes via other Buddhas or bodhisattvas (e.g., Vajrapani). This lineage-based transmission ensures the preservation of the purity and effectiveness of the teachings. Practitioners often engage in deity yoga, a meditative practice where one visualizes oneself as a deity embodying enlightened qualities to transform one's perception of reality. The tradition also acknowledges the role of feminine energy, venerating female Buddhas and ḍākiṇīs (spiritual beings), and sometimes incorporates practices that challenge conventional norms to transcend dualistic thinking.

In philosophy, desire has been identified as a recurring philosophical problem. It has been variously interpreted as what compels someone towards the highest state of human nature or consciousness, as well as being posited as either something to be eliminated or a powerful source of potential.

In Plato's The Republic, Socrates argued that individual desires must be postponed in the name of a higher ideal. Similarly, within the teachings of Buddhism, craving, identified as the most potent form of desire, is thought to be the cause of all suffering, which can be eliminated to attain greater happiness (Nirvana). While on the path to liberation, a practitioner is advised to "generate desire" for skillful ends.

The three poisons (Sanskrit: triviṣa; Tibetan: dug gsum) in the Mahayana tradition or the three unwholesome roots (Sanskrit: akuśala-mūla; Pāli: akusala-mūla) in the Theravada tradition are a Buddhist term that refers to the three root kleshas that lead to all negative states. These three states are delusion, also known as ignorance; greed or sensual attachment; and hatred or aversion. These three poisons are considered to be three afflictions or character flaws that are innate in beings and the root of craving, and so causing suffering and rebirth.

The three poisons are symbolically shown at the center of the Buddhist Bhavachakra artwork, with the rooster, snake, and pig, representing greed, ill-will and delusion respectively.
