4 hours or so. Only since there can be no attendance because of CV-19 has that come down to 2 hours or so.

But that may also be due to his concern and compassion for his listeners, live or online; he can possibly have only a very vague idea of the mental capacity of each, and none at all of any stage of magga phala attained, so he must assume that none has. Besides the diversions.

may you progress on the Path.
