Question

What is duality in Buddhist meditation?

Answer 1

"The central tenet of Madhyamika Buddhism, that samsara is nirvana, is difficult to understand in any other way except as asserting the two different ways of perceiving, dually and nondually. The dualistic perception of a world of discrete objects (one of them being me) which are created and destroyed constitutes samsara." When dualistic perceptions do not arise, there is nirvana. Put another way, "nirvana is the nondual 'true nature' of samsara."
