Samadhi in the context of "Moksha"

Mysticism encompasses religious traditions of human transformation aided by various practices and religious experiences. Popularly, mysticism is used synonymously with mystical experience, a neologism which refers to an ecstatic unitive experience of becoming one with God, the Absolute, or all that exists.

Scholarly research since the 1970s had questioned this understanding, noting that what appears to be mysticism may also refer to the attainment of insight into ultimate or hidden truths, as in Buddhist awakening and Hindu prajna, in nondualism, and in the realisation of emptiness and ego-lessness, and also to altered states of consciousness such as samadhi.

Dhyāna (Sanskrit: ध्यान) in Hinduism means meditation and contemplation. Dhyana is taken up in Yoga practices, and is a means to samadhi and self-knowledge.

The various concepts of dhyana and its practice originated in the Sramanic movement of ancient India, which started before the 6th century BCE (pre-Buddha, pre-Mahavira), and the practice has been influential within the diverse traditions of Hinduism. It is, in Hinduism, a part of a self-directed awareness and unifying Yoga process by which the yogi realizes Self (Atman, soul), one's relationship with other living beings, and the Ultimate Reality. Dhyana is also part of other Indian religions such as Buddhism and Jainism. Several other traditions introduce unique aspects and context to Dhyana, and mutually influence each other.

Buddhist meditation is the practice of meditation in Buddhism. The closest words for meditation in the classical languages of Buddhism are bhāvanā ("mental development") and jhāna/dhyāna (a state of meditative absorption resulting in a calm and luminous mind).

Buddhists pursue meditation as part of the path toward liberation from defilements (kleshas) and clinging and craving (upādāna), also called awakening, which results in the attainment of nirvana. The Indian Buddhist schools relied on numerous meditation techniques to attain meditative absorption, some of which remain influential in certain modern schools of Buddhism. Classic Buddhist meditations include anapanasati (mindfulness of breathing), asubha bhavana ("reflections on repulsiveness"); reflection on pratityasamutpada (dependent origination); anussati (recollections, including anapanasati), the four foundations of mindfulness, and the divine abodes (including loving-kindness and compassion). These techniques aim to develop various qualities including equanimity, sati (mindfulness), samadhi (unification of mind) c.q. samatha (tranquility) and vipassanā (insight); and are also said to lead to abhijñā (supramundane powers). These meditation techniques are preceded by and combined with practices which aid this development, such as moral restraint and right effort to develop wholesome states of mind.

The Noble Eightfold Path (Sanskrit: आर्याष्टाङ्गमार्ग, romanized: āryāṣṭāṅgamārga) or Eight Right Paths (Sanskrit: अष्टसम्यङ्मार्ग, romanized: aṣṭasamyaṅmārga) is an early summary of the path of Buddhist practices leading to liberation from samsara, the painful cycle of rebirth, in the form of nirvana.

The Eightfold Path consists of eight practices: right view, right resolve, right speech, right conduct, right livelihood, right effort, right mindfulness, and right samadhi ('meditative absorption or union'; alternatively, equanimous meditative awareness).

In the Buddhist tradition, the five hindrances (Sinhala: පඤ්ච නීවරණ, romanized: pañca nīvaraṇa; Pali: pañca nīvaraṇāni) are identified as mental factors that hinder progress in meditation and in daily life. In the Theravada tradition, these factors are identified specifically as obstacles to the jhānas (stages of concentration) within meditation practice. Contemporary Insight Meditation teachers identify the five hindrances as obstacles to mindfulness meditation.

Within the Mahayana tradition, the five hindrances are obstacles to samadhi. They are part of the two types of obstructions (Sanskrit: āvaraṇa), i.e. the obstacles to Buddhahood. The two types of obstructions are afflictive obstructions (Sanskrit: kleśāvaraṇa, which include the standard five hindrances) and cognitive obstructions (jñeyāvaraṇa, which can only be removed by bodhisattvas).

Paṭik(k)ūlamanasikāra is a Pāli term that is generally translated as "reflections on repulsiveness". It refers to a traditional Buddhist meditation whereby thirty-one parts of the body are contemplated in a variety of ways. In addition to developing sati (mindfulness) and samādhi (concentration), this form of meditation is considered conducive to overcoming desire and lust. Along with cemetery contemplations such as the contemplation of the nine stages of decay, this type of meditation is one of the two meditations on "the foul" or "unattractive" (Pāli: asubha).

Hinduism and Buddhism have common origins in Ancient India, which later spread and became dominant religions in Southeast Asian countries, including Cambodia and Indonesia around the 4th century CE. Buddhism arose in the Gangetic plains of Eastern India in the 5th century BCE during the Second Urbanisation (600–200 BC). Hinduism developed as a fusion or synthesis of practices and ideas from the ancient Vedic religion and elements and deities from other local Indian traditions.

Both religions share many beliefs and practices but also exhibit pronounced differences that have led to significant debate. Both religions share a belief in karma and rebirth (or reincarnation). They both accept the idea of spiritual liberation (moksha or nirvana) from the cycle of reincarnation and promote similar religious practices, such as dhyana, samadhi, mantra, and devotion. Both religions also share many deities (though their nature is understood differently), including Saraswati, Vishnu (Upulvan), Mahakala, Indra, Ganesha, and Brahma.

Buddhist ethics are traditionally based on the enlightened perspective of the Buddha. In Buddhism, ethics or morality are understood by the term śīla (Sanskrit: शील) or sīla (Pāli). Śīla is one of three sections of the Noble Eightfold Path. It is a code of conduct that emulates a natural inborn nature that embraces a commitment to harmony, equanimity, and self-regulation, primarily motivated by nonviolence or freedom from causing harm. It has been variously described as virtue, moral discipline uprightness and precept, skillful conduct. Sīla is one of the three practices foundational to Buddhism and the non-sectarian Vipassana movement; sīla, samādhi, and paññā. It is included within the Theravadin foundations of sīla, dāna, and bhavana. It is also the second pāramitā in Mahayana Buddhism.

Sīla is the wholehearted commitment to what is wholesome that grows with experience of practice. In contrast to the English word "morality" (i.e., obedience, a sense of obligation, and external constraint), Sīla is a resolve to connect with what is believed to be our innate ethical compass. It is an intentional ethical behaviour that is refined and clarified through walking the path toward liberation. Within some traditions, the true adversary is our ignorance, our clinging to beliefs, complexes and our misguided perceptions. As such, behavior is not viewed as good or evil but as skillful or unskillful.

Gorakhnath (also known as Gorakshanath (Sanskrit: Gorakṣanātha) (Devanagari : गोरक्षनाथ / गोरखनाथ), c. early 11th century) was a Hindu yogi, mahasiddha and saint who was the founder of the Nath Hindu monastic movement in India. He is considered one of the two disciples of Matsyendranath. His followers are known as Jogi, Gorakhnathi, Darshani or Kanphata.

Gorakhnath is considered a Maha-yogi (or "great yogi") in Hindu tradition. He was one of nine saints, or Navnath, in the spiritual lineage of nine masters with Shiva as their first direct teacher. Hagiographies describe him to be a person outside the laws of time who appeared on earth during different ages. He did not emphasize a specific metaphysical theory or a particular Truth, but emphasized that the unbiased search for Truth is a valuable and normal goal of man. Gorakhnath championed Yoga, spiritual discipline and enlightened guidance of a realized master (Guru) as the means to reaching samadhi or spiritual liberation.

Ashtanga yoga (Sanskrit: अष्टाङ्गयोग, romanized: aṣṭāṅgayoga, "eight limbs of yoga") is Pātañjali's classification of classical yoga, as set out in his Yoga Sūtras. He defined the eight limbs as yama (abstinences), niyama (observances), āsana (postures), prāṇāyāma (breath control), pratyāhāra (withdrawal of the senses), dhāraṇā (concentration), dhyāna (meditation), and samādhi (absorption).

The eight limbs form a sequence from the outer to the inner. The posture, asana, must be steady and comfortable for a long time, in order for the yogi to practice the limbs from prāṇāyāma until samādhi. The main aim is kaivalya, discernment of Puruṣa, the witness-conscious, as separate from Prakṛti, the cognitive apparatus, and disentanglement of Puruṣa from its muddled defilements.

Jain meditation (Sanskrit: ध्यान, dhyana) includes various practices of reflection and meditation. While Jainism considers yoga and dhyana as necessary practices, it has never been a fully developed practice, but "an adjunct to austerity" to still mental and physical activity. According to the Jain-canon, the only means to attain liberation is sukla-dhyāna, but essential knowledge of dhyana may have been lost early in the Jain-tradition, and the Tattvārtha-sūtra (2nd-5th c. CE) "states that pure meditation (sukla-dhyāna, e.g. samadhi) is unattainable in the current time-cycle." Nevertheless, sāmāyika (equanimity) is an essential practice in Jainism.

The oldest descriptions of Jain yoga and meditation can be found in the Acaranga Sutra (300 BCE), which describes the solitary ascetic meditation of Mahavira. It mentions Trāṭaka (fixed gaze) meditation, and uses the phrase "kāyaṃ vosajjamaṇgāre" (ĀS1, 9.3.7.), "an ascetic who has given up the body," which may be an early reference to Kayotsarga, "giving up the body," an essential Jain meditative practice, in which one stands motionless, signifying the death of the body, achieving tranquility and purity of mind, resembling the three limbs of dharana, dhyana, and samadhi of Patanjali's eight limb yoga. The Sutrakritanga (2nd c. BCE) mentions preksha (self-observation), and states that "the ultimate means for emancipation are dhyana, yoga and titiksa (tolerance). It also states that yoga and meditation can be completed by kayotsarga.
