Just noticed an error in my translation. Its useful to have the relevant reference materials to hand to check this out. I originally rendered this as avivartin but it should be ādhibhū(mika) . A nasty mistake. Reference to the Sanskrit identifies that this is a bodhisattva at the outset of his career which is something quite dissimilar to my rendering. I should have spotted this earlier, after all, Lancaster (1968) does list this in Appendix B. Karashima has helped resolve this issue though and I'm now glad to have this really useful book.
