The Foundations of Mindfulness

Herein, monks, when sense-desire is present, a monk knows, "There is sense-desire in me," or when sense-desire is not present, he knows, "There is no sense-desire in me." He knows how the arising of the non-arisen sense-desire comes to be; he knows how the abandoning of the arisen sense-desire comes to be; and he knows how the non-arising in the future of the abandoned sense-desire comes to be.

When anger is present, he knows, "There is anger in me," or when anger is not present, he knows, "There is no anger in me." He knows how the arising of the non-arisen anger comes to be; he knows how the abandoning of the arisen anger comes to be; and he knows how the non-arising in the future of the abandoned anger comes to be.

When sloth and torpor are present, he knows, "There are sloth and torpor in me," or when sloth and torpor are not present, he knows, "There are no sloth and torpor in me." He knows how the arising of the non-arisen sloth and torpor comes to be; he knows how the abandoning of the arisen sloth and torpor comes to be; and he knows how the non-arising in the future of the abandoned sloth and torpor comes to be.

When agitation and remorse are present, he knows, "There are agitation and remorse in me," or when agitation and remorse are not present, he knows, "There are no agitation and remorse in me." He knows how the arising of the non-arisen agitation and remorse comes to be; he knows how the abandoning of the arisen agitation and remorse comes to be; and he knows how the non-arising in the future of the abandoned agitation and remorse comes to be.

When doubt is present, he knows, "There is doubt in me," or when doubt is not present, he knows, "There is no doubt in me." He knows how the arising of the non-arisen doubt comes to be; he knows how the abandoning of the arisen doubt comes to be; and he knows how the non-arising in the future of the abandoned doubt comes to be.

Thus he lives contemplating mental objects in mental objects internally, or he lives contemplating mental objects in mental objects externally, or he lives contemplating mental objects in mental objects internally and externally. He lives contemplating origination factors in mental objects, or he lives contemplating dissolution factors in mental objects, or he lives contemplating origination-and-dissolution factors in mental objects.[21] Or his mindfulness is established with the thought, "Mental objects exist," to the extent necessary just for knowledge and mindfulness, and he lives detached, and clings to nothing in the world. Thus also, monks, a monk lives contemplating mental objects in the mental objects of the five hindrances.
