In the latest issue of enlighten next magazine there was a fascinating article called Eros, Buddha & the spectrum of love.
Ken Wilber and Andrew Cohen, the first the "pandit" (scholar), the second the guru, explain that nonduality is uniting form and formlessness. The buddha for example new emptiness, which he called nirvana. But knowing emptiness is a form of escaping samsara (suffering, taxes, sickness, bad reality shows, mass marketing); while Nonduality is knowing both nirvana and samsara - not escaping one thanks to the other.
Samsara is the world of form and the world of form is continuously evolving. Evolution and the evolutionary impulse are both forms of becoming. Samsara is the world of becoming and nirvana is the world of the unborn. True spirituality and enlightenment is thus uniting the unborn and the becoming, understanding that form and formlessness are in fact one. This is the true nature of non duality.
This insight first came to us approximately 800 years after the buddha thanks to a sage named Nagarjuna. I find it fascinating that such a radical insight comes to us from someone I've never heard of before. And again I learn of it thanks to Ken Wilber - the ultimate scholar of spirituality.
And again I am left with the feeling that Wilber talks about it while Cohen lives it...
