Story-day is for cultural exploration, puraanas and parables and finding out about leading lights in spiritual philosophy.
Yesterday, the benefits of a Guru/Master/Teacher were expounded. That was from the perspective of one who has had the great benefit of sitting at the feet of such a one. However, it was also pointed out that the Guru will always credit their Guru and that one will credit their Guru in turn - this is how parampara, the traditional lineage, comes about. The lineage of Gurudev can be traced all the way back to Adi Shankaraacharya… and he also acknowledged the masters before himself. In his text, the Vivekachoodaamani, there is an exposition on the Guru - and indeed the very first shloka, the mangala charana, extols his devotion to his own Guru.
Here now is a short video, which starts with a chanting of a few of the 108 names of the Guru, then a clip of Gurudev teaching from Vivekachoodaamani on Guru itself.
