These were a bit more useful for me. Each session has a specific mantra that Deepak explains. Oprah's part is the intro, and it is pretty pointless except so she can say she collaborated AFIACT.

Anything of this flavor comes with the obvious disclaimer. Gurus are human too, of course. In Deepak's case, there's even a documentary from his son Gotham ("Decoding Deepak") that shows that side of his father.
