" What is commonly referred to as a ‘calm mind’ or a ‘mind integrated in samādhi’ is a state of inner stability that is no longer associated with the meditation object, which merely prepared the mind by holding it steady. Once the mind has entered into samādhi, there exists enough momentum for the mind to remain in this state of calm, independent of the preparatory object, whose function is temporarily discontinued while the mind rests peacefully.
Later on, when the mind withdraws from samādhi, one can focus attention on a dhamma theme (Buddhist teachings). When this is practiced consistently with dedication and sustained effort, a mind long steeped in dukkha (stress, suffering, dissatisfaction) will gradually awaken to its own potential and abandon its unskillful ways. The struggle to tame the mind, which one experiences in the beginning stages of training, will be replaced by a keen interest in the task at hand. "
