This sacred head of Dorje Shugden can only have been fashioned by the bare hands of an extraordinary being. Whatever insanity that the great Mahasiddha ,Kyabje Phara Dorje Chang, had displayed would have been merely the perception of some. The fact that Kyabje Phara Dorje Chang was able to emerge from the haunted and ghost -ridden jungle alive and unscathed, showed him to be the great practitioner that he was..Being a great devotee to Dorje Shugden, one can well imagine his closeness to Shugden, which fueled all his actions.
To me, Kyabje Phara Dorje Chang was an amazingly great Lama and practitioner.
