Ramana Maharshi - Self Enquiry by following the clue of aham-vritti

Ramana Maharshi - Self Enquiry by following the clue of aham-vritti is just like the dog tracing his master by his scent. The master may be at some distant unknown place, but that does not stand in the way of the dog tracing him. The master's scent is an infallible clue for the animal, and nothing else, such as the dress he wears, or his build and stature, etc., counts. To that scent the dog holds on undistractedly while searching for him, and finally it succeeds in tracing him.
