Akshobhya (Sanskrit: अक्षोभ्य, Akṣobhya, "Immovable One"; traditional Chinese: 阿閦如来; ; pinyin: Āchùrúlái; Japanese pronunciation: Ashuku Nyorai) is one of the Five Wisdom Buddhas, a product of the Adibuddha, who represents consciousness as an aspect of reality.

Akshobhya appears in the Akṣobhyatathāgatasyavyūha Sūtra (Chinese: 阿閦佛國經; pinyin: Āchùfó Guó Jīng), which was translated during the second century CE and is among the oldest known Mahayana or Pure Land texts.

[1] According to the scripture, a monk wished to practice the Dharma in the eastern world of delight and made a vow not to harbor anger or malice towards any being until he achieved enlightenment.

Recently, newly discovered Gāndhārī texts from Pakistan in the Bajaur Collection have been found to contain fragments of an early Mahāyāna sutra mentioning Akshobhya.

Prior to the advent of Bhaiṣajyaguru, Akshobhya was the subject of a minor cult in Japan as a healing Buddha, though both are currently venerated within Shingon Buddhism.

Many wrathful, tantric beings are represented as blue in colour because they embody the transmuted energy of hatred and aggression into wisdom and enlightenment.
