As to whether meditation should begin with mental concentration or mental stillness, each practice is advisable at different times or during different phases of one's development. In the course of a year, the student may devote his work during some months to beginning with the first and during other months with the second. It is not possible to generalize about which one is better during any particular period; this depends entirely on individual circumstances. The best way to find out is to make an impersonal self-examination, and then follow one's own intuition.
