In Sanskrit, "nirvana" - attenuation, fading, and neither the first nor the second value does not carry negative connotations. Nirvana represents the ultimate goal of every human being, expressed in the cessation of suffering - dukkha, attachments - doshas, ​​rebirth - samsara and exclusion from the impact of the "laws of karma." Nirvana divided into upadhasheshey - extinction of human passions and apupadhasheshey - cessation of existence (Parinirvana).
Nirvana is the result of the "noble eightfold path", which is the main content of the Buddha's teachings - right view - right thinking - right speech - the right things - right living - rightattention - right meditation.
Reaching nirvana is possible only after the complete failure of the thoughts, feelings and perceptions (nirodha) and the complete cessation of these processes.Classical Buddhism considers such a possibility only for the Buddhist monk or the Buddha himself.
continued existence has reached the nirvana can not be defined in available to us terms, but can be intuitively understood by negative descriptions - attained nirvana can not be named: - existing - nonexistent - both existing and non-existent;- non-existent.
Hence, Nirvana is defined as: - not born - not manufactured - not created - not connected, characterized by a lack of affections, desires and illusions.Incomparability nirvana causes her indescribable.
Later works adherents Mahayana interpret Nirvana as: - not being, because it can not be destroyed, and not subject to decay, has no apparent reason and has its own nature (nihsvabhava) - not non-existentsincenon-existent assumes the existence of things, and not an independent - is not, and so, and others because they do not have mutually exclusive characteristics, ie,essentially indistinguishable from samsara and becomes, as such, the true nature of things.
