Achala, Krodharaja (Tibetan: tro wo gyal po me'o wa, English: the Immovable One, King of Wrath).
Very wrathful, blue in colour, with one face, three eyes, brown hair flowing upward and two hands, he holds aloft the flaming sword of wisdom in the right hand. With the left placed at the heart in a wrathful gesture he holds a vajra lasso. Adorned with a crown of skulls and gold and jewel ornaments, earrings and necklaces he wears a scarf of green silk and a lower garment of tiger skin. Kneeling with the left knee pressed down and the right raised he dwells upon a sun and lotus seat as if about to stand, completely surrounded by the flames of pristine awareness atop a throne supported by the four worldly deities, Brahma, Vishnu, Indra and Shiva. The front is adorned with a sword motif. At the right and left sides are four Achalas, all in the same appearance save for the colours, red, yellow, green and white.
Seated at the top are the Five Tantric Buddhas, from left to right, Ratnasambhava, Vairocana, Akshobhya, Amitabha and Amoghasiddhi. Below, on both sides are two goddesses with three faces and six hands. Parallel to the throne are two wrathful black goddesses, naked, with one face and two hands holding a stick in the upraised right and a lasso in the left, standing.
At the bottom left is the elephant headed wealth deity Ganapati of the Atisha Lineage, white in colour, with one face and four hands. In the middle is the bodhisattva of wisdom Manjushri, yellow, holding aloft a sword and Prajnaparamita book. At both sides are skullcups filled with wrathful offerings of the five senses. To the right is the wrathful protector Chaturbhuja Mahakala, blue-black, with one face and four hands, seated in a relaxed posture.
Krodharaja Achala is found in the Siddhaikavira Tantra, commonly known as the White Manjushri Tantra of the Kriya classification. It is from here that he takes on his role as a remover of obstacles and the special protector for the practices of Manjushri. In Anuttarayoga, Achala is also known as Candamaharoshana from the tantra of the same name, and has the same appearance with an added consort and nine-deity mandala. The Kriya Tantra practice of Achala was popularized by Lord Atisha (982-1054), the founder of the Kadampa School and also by lobpon Sonam Tsemo of Sakya (1142-1182).
