None. There is no single earthly mountain or temple uniquely associated with Candraprabha independent of the Medicine Buddha tradition. He is venerated in all major Medicine Buddha halls (药师殿) where Bhaisajyaguru is enshrined, appearing as the right-hand attendant alongside Suryaprabha on the left.

This entry is part of the Fo (佛) Scroll. The primary relation is with the Medicine Buddha (药师佛), who is the central figure of the Eastern Pure Land and the object of Candraprabha's attendant service. The complementary counterpart is Suryaprabha Bodhisattva (日光菩萨), with whom Candraprabha shares the twin-attendant role and a yin-yang-like balance of solar and lunar qualities. Candraprabha's past life as King Moonlight is a separate figure that appears in the Sutra of the Wise and the Foolish. His cultivation method, the Moonlight Samadhi, is a specific meditative practice that can be found under that term. Readers interested in the broader context should consult the entries for Bhaisajyaguru Buddha and Suryaprabha Bodhisattva.

Candraprabha holds the rank of Pu Sa (Bodhisattva)—a being who has voluntarily delayed final liberation to serve the liberation of others. His cultivation spans immeasurable kalpas, oriented entirely through the Moonlight Samadhi: a meditative method that generates a state of pervasive, non-aggressive clarity. Unlike Luo Han (Arhats), who freeze all karmic generation, or Fo (Buddhas), who have exited the system entirely, Candraprabha remains in the world as a steady, cooling presence. His Bodhisattva path is defined not by a spectacular vow but by the silent, permanent function of lowering the temperature of suffering wherever it arises—a form of compassion without heat, without struggle, without resistance.

Before his bodhisattva career, in a past life recorded in the Sūtra of the Wise and the Foolish (《贤愚经》), Candraprabha was born as King Moonlight (月光王), a sovereign renowned for his limitless generosity. He gave away his head, his eyes, his marrow—every part of his body—without hesitation, practicing the perfection of dāna (布施波罗蜜) to its ultimate conclusion. This life was the seed of his awakening: he saw that even the most precious physical form is transient and that clinging to it only perpetuates suffering. There is no recorded tonsure or formal ordination in that life; his entry into the path was a direct seeing of impermanence through the act of giving itself. The ritual dimension of his renunciation was not a monastic ceremony but the systematic dismantling of attachment through repeated, voluntary sacrifice. After that life, he entered the bodhisattva stream and took birth in the Pure Land of the Medicine Buddha, where he continues his practice.

Candraprabha's primary method for breaking through appearances (破相) is the Moonlight Samadhi (月光三昧). In this practice, the meditator visualizes a full, cool moon-disk—not as an external object, but as the very nature of one's own awareness. The moon is not hot like the sun; it does not burn away defilements through force. Instead, it permeates. As the visualization deepens, the practitioner experiences a radical shift: the heat of desire, anger, and ignorance—phenomena that once felt solid and overwhelming—begins to dissolve like mist under a steady, cold light. The body cools. The mind becomes still. The world, which had seemed to press upon the senses with unbearable weight, is seen to be as insubstantial as a reflection on water. This is the direct cognition of emptiness (Kong) through the metaphor of lunar reflection: the moon does not move, yet it appears in a thousand rivers. Awareness does not grasp, yet it illuminates all phenomena. The key realization is that the cooling itself is not an action; it is the natural state when the heat of grasping is released.

Candraprabha did not announce a formal, irreversible Hong Yuan (宏愿) like those of Kṣitigarbha or Avalokiteśvara. His commitment is implicit and structural: as the right-hand attendant of the Medicine Buddha, he has accepted the permanent duty of cooling the karmic fevers of beings in the Eastern Pure Land and beyond. This is not a one-time contract but a continuous function—a bit like the way the moon does not choose to shine, but simply does so by being what it is. His moon-disk consciousness acts as a natural damper on the turbulence of sentient existence. In the ritual manuals of the Medicine Buddha practice, Candraprabha is invoked to remove calamities and prolong life (消灾延寿), which means he actively intercepts the karmic momentum that would otherwise express itself as disease, violence, or early death. He absorbs the heat of these retributions and transmutes it into cool, sustaining light. The volume of this absorption is beyond measure; he works not on individual cases but on the atmospheric pressure of suffering in entire realms.

Candraprabha abides in the Pure Crystal Palace of the Eastern Pure Land (净琉璃世界), the Buddha-field of Bhaisajyaguru (药师佛), the Medicine Master. This realm is not a transcendence of the Three Realms but a purified domain within the eastern quarter of the cosmos, where the laws of karma are mitigated by the Medicine Buddha's vows and the twin powers of sunlight and moonlight. Candraprabha shares this space with Suryaprabha Bodhisattva (日光菩萨), his solar counterpart, who governs the daytime aspect of the Pure Land. Together they form the "Sun and Moon Twin Attendants" (日月二胁侍), the two primary Bodhisattva disciples of the Medicine Buddha. Their dharma transmission is not through an earthly lineage of monks but through the ritual texts of the Medicine Buddha sūtras and the Yogacara practices associated with the Pure Land. Candraprabha's relationship with other awakened beings is functional: he works silently alongside Suryaprabha, complementing the latter's intense, burning awareness with permeating, reflective coolness.

The most famous recorded episode from Candraprabha's path is his past life as King Moonlight (月光王), in which he gave away his own head to a brahmin who demanded it. This story, found in the Sūtra of the Wise and the Foolish (《贤愚经》), is not a random act of violence but the climax of a life dedicated to the perfection of generosity. The king did not suffer; he offered his head with the same ease as one offers a flower, having already seen through the illusion of self. Another key event is his ongoing function in the Medicine Buddha practice: in the Bhaisajyaguru Sūtra, Candraprabha and Suryaprabha together pledge to protect all beings who recite the Medicine Buddha's name, ensuring that they never fall into the three lower realms. There is no record of a single dramatic conversion of a famous being; instead, Candraprabha's presence is felt in the countless small moments when rage subsides, when fever breaks, when a mind that was burning suddenly becomes quiet. His greatest deed is the cumulative, invisible cooling of the world's heat.

Candraprabha's interaction with the other cosmic paths is minimal but structured. With the Daoist Celestial Bureaucracy (仙道/神道), there is no direct conflict or cooperation; the Medicine Buddha's Eastern Pure Land is a separate jurisdiction. However, the Medicine Buddha practice is often used by Daoist practitioners for healing, creating a practical overlap. With the Underworld (幽冥地府), Candraprabha's function is indirect: his moonlight is said to cool the flames of the hells, offering temporary relief to beings undergoing fiery karmic retribution, but he does not intervene in the judgment process itself. He does not teach or convert hell-beings; he simply lowers the temperature of their suffering. With mortal regimes, he is not a political figure; his presence is felt through the quiet devotion of lay practitioners who recite the Medicine Buddha sūtra and visualize the moon. With Mara (魔道), his approach is not exorcism but transformation: the heat of demonic hatred, when touched by his moonlight, tends to crystallize into stillness and, eventually, dissolve. Where Suryaprabha would burn the demon, Candraprabha would cool its fire until it becomes water.

Candraprabha's current Bodhisattva fruition is stable and not deepening in any visible sense; he is a full attendant of a Buddha, which means his practice is already complete in its function. His Pure Land, the Eastern Pure Crystal Palace, is a permanent domain sustained by the Medicine Buddha's vows, not expanding but also not decaying. Within the Mahāyāna Buddhist framework, Candraprabha belongs to the space of the "Three Saints of the East" (东方三圣) alongside Bhaisajyaguru and Suryaprabha, occupying the right-hand position. In the horizontal system of the Three Buddhas, he is part of the Eastern group; in the vertical system, he has no specific temporal node—he is present for the entire duration of the Medicine Buddha's teaching. His dharma lineage continues through the ritual texts of the Medicine Buddha tradition, which remain actively practiced in East Asian Buddhism today, particularly in China, Korea, and Japan.
