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).
