Selected Scriptures from the Pali Canon
Introduction to
the Sutta Pitaka and Pali Canon
Majjhima Nikaya:
One of the most important suttas of the Pali Canon in which the Buddha explicitly declares the four foundations of Mindfulness as the 'direct path for the surmounting of sorrow, for the attainment of the true way, for the realization of Nibbana.'
A short well-expounded sutta on the futility of thinking of the past and future and that real happiness and inner peace can only be realized by dwelling in the present moment.
