Some Discomfort

Some discomfort is good.
That from recognising Dukkha drives us to Nirvana.

Some discomfort is not good.
That from denying Dukkha keeps us from Nirvana.- Stonepeace

Some reject the Dharma due to discomfort with its reality check on Dukkha, that life is prevalent with dissatisfactions, which is the First Noble Truth. Due to this denial, Nirvana, which is the end of Dukkha (the Third Noble Truth), is always far away.
