"Having the right attitude is essential for success in meditation. Although it is necessary to motivate ourselves to meditate, samâdhi will not arise from ego-based craving for altered states of consciousness or for the repetition of previously experienced peaceful states. This craving will actually increase stress. There is too much desire and sense of self.
The quickest way to make progress in meditation is to be perfectly content, putting energy into being mindful in the present moment, and not hoping for or expecting anything."
