When the historical buddha is depicted with his left hand in the meditation gesture and his right hand ‘calling Earth to witness’ he looks the same as Akshobhya if there is a vajra sceptre in front of him (unless we can clearly see wheels of dharma on the sole of his feet and the palm of his left hand).
Sometimes, the vajra is rather big compared with the rest of the sculpture.
On other occasions, only half of it is cast and it looks rather flat. The above figure has silver-inlaid eyes and urna, cold gold on his face and neck, his nails and the beading on the hem of his sanghati are made of copper.
The vajra sceptre may be on the upper rim of the lotus pedestal. We can see that the above has a dharmacakra on the sole of his right foot, which identifies him as Shakyamuni.
