There are not two realities, but there are, Madhyamaka teaches, two ways of seeing, of experiencing, of understanding the one reality: there are two truths, conventional everyday truth (samvriti-satya) and ultimate truth (paramartha-satya). In our everyday application of conventional truth, though we are aware of the intrinsic emptiness of all dharmas or phenomena since we know that all things are interdependently arisen and exist conceptually only by virtue of our idea of them or of their alleged opposite, we nevertheless do take into account and make use of the relative, conceptual aspects of phenomena in our commonplace interaction with other sentient beings and with our environment. As a matter of fact, the Noble Eightfold Path operates throughout exclusively at the level of conventional truth. As we advance along the Buddha’s Middle Way responding to his promise of Nirvana by ridding ourselves of the so-called ten fetters (dasha-, dasasamyojana) that restrict us to Samsara, the fallacies in our perception of Samsara are progressively transformed, purified first into conventional truth, and it is through conventional truth that we shall eventually come to understand the non-conceptual import of ultimate truth. The dialectic of Madhyamaka, with its exhaustive analysis of the nature of reality, indeed takes place at the level of conventional truth. By ultimate truth is meant our awareness of the underlying field of experience where all phenomena stripped of their relative aspects are known to happen: it is our insight into the void beyond all concepts. This field of experience where the real events are known to take place is that of non-dual emptiness, advayata, shunyata, the realm of prajña, non-dual, contentless intuition. To experience existence at this level, which we can truly say lies between the notions of being and non-being, is nothing less than Nirvana.  ~ @advayavada
