GVK is a poetical rendering by Muruganar of the teachings he heard from Ramana Maharshi. It has been translated by David Godman et al, and by Sadhu Om and Michael James.
Sadhu Om was another disciple of Ramana Maharshi and close associate of Muruganar.
I was not aware that Sadhu Om had written a Tamil prose rendition of GVK, arguably making it easier to follow than the original. I stumbled across Robert Butler’s translation of this work, published in 2023. It reads very well, and at a few points, he has included Sadhu Om’s commentary and that of Muruganar – when they are needed to clarify the intent.
