It happens to most sadhaks that in particular parts of the day they feel concentrated and get results, and in others that condition is not there. This is especially in the earlier stages of the progress. It is only after the higher consciousness, peace etc. have settled in the being that one can usually be at all times in the active condition of sadhana.
