Consciousness is merely to know

The non-dual and life-affirming philosophy way of life we call Advayavada Buddhism, to which we wholeheartedly adhere, is derived from Nagarjuna's Madhyamaka, or philosophy of the Middle Way. For the Advayavadin, Samsara and Nirvana are not different objectively, and there is, in Advayavada Buddhism, no talk of a mind separate from the body. Mind is merely to think and to think is a manifestation of being, as are to walk, to talk or to sleep. It is one of the many ways in which the one 'person' exists, i.e. becomes over time. To the Advayavadin, to say that the mind has or does things, sounds like saying that not one but one's running does the sprinting. This is particularly true when he or she hears other Buddhists saying, for example, that not they but their consciousnesses will eventually enter Nirvana or be reborn or something. However important, consciousness is merely to know, the activity of knowing going on in our brains. Mind (to think) and consciousness (to know) are not things but functions, activities, deeds, events without any substance or corporeality. Also Buddha-nature is insubstantial and not something different or separate from Reality - it is but a name for Reality as it manifests itself in sentient beings. Nirvana, for the Advayavadin, is indeed to live fully in accordance with one's Buddha-nature. (from the Advayavada Buddhism website)
