Happy guru

When a disciple very perfectly makes progress in spiritual life, this
gladdens the spiritual master, who then also smiles in ecstasy, thinking,
“How successful my disciple has become!” He feels so glad that he smiles as
he enjoys the progress of the disciple, just as a smiling parent enjoys the
activities of a child who is trying to stand up or crawl perfectly.
