Dada Bhagwan said this quote

One has to attain an ego-less state (nir-ahankari), attaining a nir-maani state (a desire-free state that wants importance from others) is not enough. The egoism one has of being nir-mani is very subtle. The external ‘horns’ are worn down but the internal ones still remain. The inner ‘horns’ will cause an internal biting.
