Akshobhya is second Dhyani-Buddha. He is represented seated, like other Dhyani-Buddhas, with legs locked and feet apparent [lotus posture]. His left hand lies on his lap in meditation mudra [posture]. His right touches the earth with the tips of the outstretched fingers, the palm turned inward. This is called bhumisparsa or witness mudra, and is the same pose of the hands that of Sakya-muni, when representing his invoking the Earth to bear witness that he had resisted the temptation of the Evil Mara. Akshobhya some time also take another form of Sakya-muni Buddha called "Vajrasana" [diamond throne]. The attitude is the same as the above, but before him on the lotus throne lies a vajra, or it may be balanced in the palm of the left hand lying in meditation mudra on his lap.
Akshobhya is given blue body color, as this color is believed to emanate from him also among the six elements of which man is composed, the element of air is believed to emanate from Akshobhya. He is the perfected state of our faculty of consciousness [sound] and our aggregate of form.
Akshobhya was first mentioned in the wisdom book Prajnaparamita sutra in the beginning, and later in the Saddharma, pundarika, as well as in the smaller Sukhavati vyuha, where his glorious paradise in the East called Abhirti is described. According to the system of five dhyani-Buddhas, his Dhyani-Boddhisattva is Vajrapani.
