`   ==Sitting in Perfect Knowledge==  reverted my edit. I had claimed that Nirvana is not knowledge. However, 216.254.121.169 claims that Nirvana is ``the end of 'avidya' or root cause of suffering.`` But what, according to Siddhartha, is the root cause of suffering? According to the second Noble Truth, attachment or desire is the root cause of suffering. So, Nirvana is the end of attachment or desire, and as a result, the end of suffering. The Buddha is not sitting in perfect knowledge. The Buddha is sitting in perfect apathy as a result of his perfect knowledge. If the article claims that the Buddha's Nirvana is, itself, perfect knowledge, then it is grossly misleading all readers. Lestrade`
