Lokeśvara ("Lord of the World") and Chenrezig (in Tibetan) is a tenth-level bodhisattva associated with great compassion (mahakaruṇā), and often with Amitabha Buddha in Mahayana Buddhism. Avalokiteśvara has numerous manifestations and is depicted in various forms and styles. In some texts, he is even considered to be the source of all Hindu deities (such as Vishnu, Shiva, Saraswati, Brahma, etc).

In modern Cambodia, the four faces of Avalokitesvara (or Avaloksvara, Loksvara) are usually represented at the top of a pagoda or a stupa, as protector of all the planets. When Brahmanism was popular, these faces were considered as the faces of Brahma. In ancient Khmer art, he is represented with two, four, six or eight arms in freestanding sculptures, and ten arms in temple bas-reliefs such those at Banteay Chhmar. The massive stone faces of Bayon are believed to represent Lokeshvara.

Khmer worship of Lokeshvara reached a peak during the reign of Jayavarman VII. Due to his healing powers, the he was given a predominant position in the scenes carved on the chapels of the hospitals built by this king. Lokeshvara was also omnipresent at Neak Poan Temple, whose waters could cleanse the sins and diseases of the pilgrims. Jayavarman VII dedicated the temple of Preah Khan Temple to the memory of his father, deified in the likeness of Lokeshvara.

A sculpture from Prei Monti (Roluos), late 12th-early 13th century, at the National Museum of Cambodia (piece Ga.2424), represents three adorned divinities: Buddha shelled by the Naga in the middle, Lokesvara to the right of the Buddha, and Prajnaparamita to the left. Lokesvara's attributes are the lotus bud, rosary, vase with water of immortality (amrta) and book. Those of Prajnaparamita include the book and the lotus bud.

While Avalokiteśvara was depicted as male in India, and male or female in Tibetan tradition, the deity is often depicted as a female figure in East Asian Buddhism, known as Guanyin /Kuan Yin in Chinese, Kannon in Japanese, Gwaneum in Korean and Quan Am in Vietnamese. In Sri Lanka, Natha literally means ‘no form’ or ‘no shape’, thus associating Avalokiteśvara with Maitreya, the next Buddha

Avalokiteśvara is also known for his popular mantra, oṃ maṇi padme hūṃ, which is the most popular mantra in Tibetan Buddhism.

Bhikshatana-murti is the representation of the Hindu god Shiva as the "Supreme Beggar", a nude, four-armed male figure (Kapali mendicant) with a begging bowl, surrounded by demonic followers and love-sick women.

Contrary to Shiva's other avatar Bhairava, fierce and threatening, Shiva as Bhikshatana is gentle, so handsome he easily seduces the female companions of forest ascets while wandering as a mendicant to atone for his sin of severing Brahma's fifth head on his way to the holy city of Varanasi. After this experience, triumphan Bhikshatana establishes the worship of the Linga or, according to other traditions, becomes Nataraja, the "Cosmic Dancer".

A bas-relief representing Bhikshatana seducing the wives of sages has been identified by Madeleine Giteau in the southwestern pavilion of Angkor Wat's third precinct. Jean Boulbet has identified representations of Shiva as Bhikshatana at Kbal Spean. Several bronze statues of Bhikshtana dating back from Cambodia's 12th century are hosted in museums worldwide, including the Minneapolis Institute of Art (MIA).

A candi is a Hindu or Buddhist temple in Indonesia, particularly in Central and Eastern Java, mostly built during the "Hindu-Buddhist period"(between 4th and 15th centuries).

The official definition is an ancient stone building used for worship, or for storing the ashes of cremated Hindu or Buddhist kings and priests, with a larger archaeological definition as Hindu and/or Buddhist sacred structures for religious rituals and ceremonies. In Balinese architecture, the candi is a stone or brick structure of one cell-shrine with portico and pyramidal roof, located within a pura.

The candi architecture reflects a form of syncretism typical of Java. As V.M.Y Degroot, noted in 2009 "the Indian concept of space appears to have been more directly implemented into Buddhist architecture than in Hindu shrines. The layout of the large Buddhist temples of Central Java indeed depicts a rather concentric view of the cosmos, compatible in most respects with Indian descriptions of the universe. The Hindu religious compounds, on the contrary, emphasize a different approach in which the idea of progression is reinforced, as well as the association of sanctity with the rear of the temple compound, as so frequently found in East Java."
