The Buddha describes the four establishments of mindfulness to be cultivated in detail, namely - mindfulness of the body, mindfulness of the felt experience, mindfulness of the mind, and mindfulness of the mental qualities.

The Buddha details a comprehensive training in mindfulness of the body—from breath and postures to anatomical reflection and charnel-ground contemplations. He explains how this cultivation steadies the mind and leads to ten benefits culminating in the four jhānas and final liberation.

The Buddha's most detailed exposition of the four establishments of mindfulness. This extended version includes comprehensive definitions of the Four Noble Truths, the Noble Eightfold Path, and the four jhānas within the framework of mindfulness practice.
