I think that Francis is great but he doesn't (as far as I know) provide a systematic approach, although, I understand that he teaches Kashmiri Yoga, which I tried out on a retreat with Rupert Spira.
What I love about AYP is that it teaches an integrated step-by-step approach to non-duality, which is missing from the Advaita scene (or at least, I've missed it if it's there).
For me, meditation is the link to Advaita and the missing ingredient.
From what I understand, many of the contemporary teachers have put in a great deal of spiritual practice prior to "enlightenment" or just "dropped lucky". Maybe those who dropped lucky did it in a previous lifetime and can't remember it now?
I love listening to Francis's satsangs, they're truly inspirational and full of Light and Love (and common sense).
I'd signed-up to go on a retreat with him this Xmas in Paris because I wanted to meet him in person (and catch up with some old friends) but it's fallen through unfortunately. I also wanted to meet him as he's Rupert Spira's teacher and I'd certainly count Rupert as one of mine. Again, he's full of Light and Love (and common sense).
I've spent a long time studying Atma Darshan and Atma Nirvriti and I can't remember anywhere where Krishna Menon says that the presence of an external Guru is essential. I'll go back and have a read through and if I find it I'll post again.
I'd agree that the Guru is indeed within and that meditation is the road to Her/Him.
