Over the summer I've been listening to an fascinating audio series on the future of spirituality in an evolutionary context. Since I always have my own challenges in meditating and overcoming ego I've found them very helpful.
You can download free meditation by Craig Hamilton - awakening to the great perfection.
Speakers in the series have included Ken Wilber, Michael Murphy, Andrew Hamilton and Genpo Roshi. All new speakers to me except Ken Wilber so it's opened up many lines of enquiry for me.
I hope you find it interesting too.
