For me, the N8P has been the best form of therapy. Replace those negative mind states with wholesome ones. Change that downer of a radio station to something more wholesome.
6. Right Effort (samma-vayama)
1) To prevent unwholesome states from arising: the Five Hindrances, the Ten Fetters/Ten Defilements
2) To abandon unwholesome states that have arisen
3) To arouse wholesome states that have not yet arisen: the Brahma-Viharas, the Four Foundations of Mindfulness, the Noble Eightfold Path, etc. - especially to arouse the Seven Factors of Enlightenment leading to jhana, serenity and insight.
4) To maintain and perfect arisen wholesome states
7. Right Mindfulness and Self-awareness (samma-sati) - The Four Foundations of Mindfulness:
1) Mindful contemplation/awareness of the body (kaya): breath meditation, the four postures, clear comprehension in all bodily activities, anatomical contemplations, the four elements, the cemetery contemplations
2) Mindful contemplation/awareness of physical sensations/emotional feelings (vedana): pleasant, unpleasant, neutral sensations (the triggers for greed, hatred and delusion)
3) Mindful contemplation/awareness of mind states (citta): greed/non-greed; hatred/non-hatred; delusion/non-delusion; drowsiness/distraction; divine/not divine; surpassed/unsurpassed; absorbed or ecstatic (jhana)/unabsorbed or non-ecstatic; liberated/un-liberated
4) Mindful contemplation/awareness/investigation of the Five Dhammas (dhammas):
The Five Hindrances - awareness of their arising and passing away; understanding what causes a hindrance to arise and pass away; and how a future arising of a hindrance can be prevented.
The Five Aggregates of Clinging - seen as arising and passing away; that they are impermanent, suffering & non-self.
The Six-sense Bases - awareness of any fetter generated by them; that they are impermanent, suffering & non-self.
The Seven Factors of Enlightenment - to be developed (mostly come from the attainment of jhana)
The Four Noble Truths - to be utterly understood.
