These two mental states are conducive to correct knowledge. Which two?
Peace and clarity.By developing peace, what purpose is served? Mind is purified.
By purifying mind, what purpose is served? Craving is abandoned.
By developing clarity, what purpose is served? Wisdom is developed.
By developing wisdom, what purpose is served? Ignorance is abandoned.
Defiled by craving, the mind is not released [from emotional agitation], and defiled by ignorance, wisdom is not developed.
Thus, abandoning craving through peace, there is liberation of the mental fluctuations, and abandoning ignorance through clarity, there is liberation by wisdom.—Buddha
Shakyamuni, Vijjābhāgiya Sutta
