It is first important to clearly understand, through study, what is involved in meditation. There are many aspects of Buddhist teaching and practice, but when we begin to meditate, we should concentrate on one particular aspect. If we jump from practice to practice we will never progress. Instead, we should choose a particular meditation practice and concentrate on that, doing our other commitments rather quickly and spending most of our time on the principal practice. If we constantly change our practice after becoming dissatisfied this will become habitual, we will never accomplish our aim and in the process will waste considerable time. Having chosen a practice and begun meditation, difficulties will arise, but at that time we must make additional effort and not simply abandon our practice. If we persevere, we will become accustomed to the practice and it will become easier. It is also possible that occasionally we may become confused about our object of meditation. Having initially made some progress, interferences set in and it all begins to seem fruitless. Here again, we must apply additional effort and carry on.
