This is the one-way path for the purification of beings, for the surmounting of sorrow and lamentations, for the passing away of pain and dejection, for the attainment of the true way, for the realization of Nibbana – namely, the four establishments of mindfulness.
What are the four? A person dwells contemplating the body in the body, ardent, clearly comprehending, and mindful, having subdued longing and dejection in regard to the world. He or she dwells contemplating feelings in feelings, ardent, clearly comprehending, mindful, having subdued longing and dejection in regard to the world. He or she dwells contemplating mind in mind, ardent, clearly comprehending, mindful, having subdued longing and dejection in regard to the world. He or she dwells contemplating phenomena in phenomena, ardent, clearly comprehending, mindful, having subdued longing and dejection in regard to the world.
[In the Buddha’s Words., p. 281]
