What does the title Aksobhya Buddha denote? Which great bodhisattva did hail from his domain?

Aksobhya Buddha is translated as the Unmoved Tathagata, thus named

because of his original vow forever unchanging and fearless toward

anger and anxiety of all living beings.

One of the most reputable great bodhisattvas hailing from the domain

of Aksobhya Buddha was the kulapati in Sanskrit or householder

Vimalakirti, who sought rebirth in the saha world (see Chapter 12, On

the Domain of Aksobhya Buddha, Sutra of Vimalakirti).
