I have heard that one night, when everyone was attending to Acharya Maharaj, somebody knocked down a bottle of oil The oil spilled out, since the bottle was uncorked. The attendants were a little disconcerted, but Acharya Maharaj continued to smile. Next morning, after the rite of veneration of the Acharya, he recalled the incident and observed. See just as you need to cork a bottle to keep its valuable contents from spilling, you must use the instrument of reprimand (stern discipline) to ensure that a disciple does not become self-willed and stray from the path of salvation.
Acharya Maharaj had made use of a banal incident that of the knocking down of a bottle, to deliver this profound sermon. This is his forte!
To cork/to reprimand – There is a subtle word play here on the Hindi wames daat (cork) and daant (reprimand).
