The 2 types of meditation that I practice I are mindfulness and concentration.
Mindfulness practice has enabled me to become aware of the arising of unskillful compulsions, the habitual patterns of thought which give rise to them and to halt their progress.
Concentration practice, on the other hand, builds the muscle of attention so that it becomes easier to stay focused and fully absorbed on whatever target you select.
I have found that the combination of the 2 has enabled me rewire less skillful habitual patterns of thought and to replace them with more skillful patterns.
