Lekhraj Visions

Is there an authentic date and account of Lekhraj (Brahma) visions?
Did the visions kick start the Yagya or did they come later?
Of course the BKWSU version of events can not be trusted, so I am not particularly interested in that. Only for comparison.
I read that Om Radhe chanting of Om caused the first trance state in a young female whilst Lekhraj was away on travels.
