Karuṇā in the context of "Yab-Yum"

Amitābha (Sanskrit pronunciation: [ɐmɪˈtaːbʱɐ], "Measureless" or "Limitless" Light), also known as Amituofo in Chinese, Amida Butsu in Japanese, Amita-bul in Korean, A Di Đà Phật in Vietnamese, and Öpakmé in Tibetan, is one of the main Buddhas of Mahayana Buddhism and the most widely venerated Buddhist figure in East Asian Buddhism. Amitābha is also known by the name Amitāyus ("Measureless Life").

Amitābha is the main figure in two influential Indian Buddhist Mahayana Scriptures: the Sutra of Measureless Life and the Amitābha Sūtra. According to the Sutra of Measureless Life, Amitābha established a pure land of perfect peace and happiness, called Sukhāvatī ("Blissful"), where beings who mindfully remember him with faith may be reborn and then quickly attain enlightenment. The pure land is the result of a set of vows Amitābha made long ago. As his name means Limitless Light, Amitābha's light is said to radiate throughout the cosmos and shine on all beings. Because of this, Amitābha is often depicted radiating light, a symbol for his wisdom. As per the name Amitāyus, this Buddha is also associated with infinite life, since his lifespan is said to be immeasurable. Amitābha's measureless life is seen as being related to his infinite compassion.

Guanyin (Chinese: 觀音; pinyin: Guānyīn; Jyutping: Gun1 jam1) is a common Chinese name of the bodhisattva associated with compassion known as Avalokiteśvara (Sanskrit: अवलोकितेश्वर). Guanyin is short for Guanshiyin, which means "[The One Who] Perceives the Sounds of the World". Originally regarded as male in Indian Buddhism, Guanyin has been more commonly depicted as female in China and most of East Asia since about the 12th century. Due to sociogeographical factors, Guanyin may also be historically depicted as genderless or androgynous. On the 19th day of the sixth lunar month, Guanyin's attainment of Buddhahood is celebrated. Guanyin has been incorporated in other religions, including Taoism and Chinese folk religion.

Some Buddhists believe that when one of their adherents departs from this world, they are placed by Guanyin in the heart of a lotus and then sent to the western pure land of Sukhāvatī. Guanyin is often referred to as the "most widely beloved Buddhist Divinity" with miraculous powers to assist all those who pray to her, as is mentioned in the universal gate chapter of the Lotus Sutra and the Kāraṇḍavyūha Sūtra.

Eastern esotericism is a term utilized by various scholars to describe a broad range of religious beliefs and practices originating from the Eastern world, characterized by esoteric, secretive, or occult elements. The classification of Eastern esotericism presents challenges, as it is influenced by varying geographical and cultural definitions of "Eastern" and "Western" contexts, particularly in relation to Islamic nations. The delineation of esotericism itself can vary among scholars, with some arguing that the concept is predominantly rooted in Western traditions. This perspective raises important questions regarding the applicability of a Western framework to non-Western practices, potentially leading to classifications that may not accurately reflect the complexities of these traditions. Conversely, other scholars propose a more globalized viewpoint, suggesting that comparable systems of secret knowledge and mystical practices exist across different cultures and warrant examination within a unified framework.

Despite these ongoing debates, the concept of Eastern esotericism has been adopted by many scholars as a relevant category for investigating the nuanced dimensions of spiritual life in various Eastern traditions. This includes elements found in Hinduism and Buddhism, where secret teachings, initiatory rites, and mystical experiences are significant. Additionally, Eastern esotericism encompasses a variety of ethnic religions and syncretic systems that integrate indigenous beliefs with other spiritual influences, thereby broadening the scope of study in this area. Overall, the term serves as a foundation for exploring the diverse and intricate landscape of esoteric thought and practice across the Eastern world.

The brahmavihārā (sublime attitudes, lit. "abodes of Brahma") is a series of four Buddhist virtues and the meditation practices made to cultivate them. They are also known as the four immeasurables (Pāli: appamaññā) or four infinite minds (Chinese: 四無量心). The brahmavihārā are:

1. loving-kindness or benevolence (mettā)
2. compassion (karuṇā)
3. empathetic joy (muditā)
4. equanimity (upekkhā)

According to the Metta Sutta, cultivation of the four immeasurables has the power to cause the practitioner to be reborn into a "Brahma realm" (Pāli: Brahmaloka).

In Buddhism, Avalokiteśvara (meaning "the Lord who looks down", IPA: /ˌʌvəloʊkɪˈteɪʃvərə/), also known as Lokeśvara ("Lord of the World") and Chenrezig (in Tibetan), is a Bodhisattva associated with Great Compassion (mahākaruṇā). Avalokiteśvara has a vast number of manifestations (e.g., the 108 forms of Avalokiteśvara) and is depicted in various forms and styles across Buddhist traditions of different cultures. In Mahayana and Vajrayana Buddhism, Avalokiteśvara is also considered a manifestation of Amitabha Buddha for the purpose of Dharma teaching, and an emanation from Vairocana Buddha as an embodiment of the Miraculous Observing Wisdom (妙觀察智).

In East Asian Buddhism, Avalokiteśvara is known as 觀音 (an abbreviation for 觀世音), pronounced Gwoon Yaam in Cantonese, Guanyin in Mandarin Chinese, Kannon in Japanese, Gwaneum in Korean, and Quan Âm in Vietnamese. In the traditional cultures of these Asian countries, there is a female form of Avalokiteśvara depicted as a divine mother in a white robe, called White-Robed Avalokiteśvara or Southern Sea Avalokiteśvara. This female form of Avalokiteśvara is worshiped widely in East Asian religions including Taoism and Chinese folk religion.

The Kadam school (Tibetan: བཀའ་གདམས་པ་, Wylie: bka' gdams pa) of Tibetan Buddhism, or Kadampa was an 11th century Buddhist tradition founded by the great Bengali master Atiśa (982–1054) and his students including Dromtön (1005–1064), a Tibetan Buddhist lay master. The Kadampa stressed compassion, pure discipline and study. By the 15th century, Tsongkapa is credited with synthesizing and folding Kadampa lineages into the Gelug school.

The most evident teachings of that tradition were the graduated teachings on the Mahayana path. These special presentations became known as lojong (mind training) and lamrim (stages of the path). Kadam masters like Atiśa also promoted the study of madhyamaka philosophy. According to Ronald M. Davidson, "Atiśa's coming to Tibet in 1042 was the threshold moment in the efflorescence of Buddhism and provided a stable foundation for monastic scholarship for the next thousand years."
