It is possible to experience a moment of true presence through special concentration achieved by the use of exercises, such as those to which Edward Salim Michael gave exposition in his books. Indeed, only by continuous concentration will the seeker be able to sense the difference relative to his ordinary state, and begin to feel in what way he usually “sleeps” inside himself without knowing it.
Inner Awakening and Practice of Nada Yoga – Chapter 10
The person who succeeds in recognizing clearly within herself an entirely unaccustomed state of presence, an intense presence, and a keen consciousness of herself that has pulled her from her ordinary state of being and feeling, has gained the most precious thing that can exist in the life of a human being.
The Supreme Quest – Chapter 20
The efforts the seeker must make to perform these kinds of exercises will allow her to realize that the resistance encountered in remaining present and concentrated is also there during her seated meditation. However, as, during her meditation, her attention is not solicited with the same exigency as during these concentration exercises, the resistance within her will appear considerably less strong and, in this way, less evident, and she will not notice it with the same clarity as when she is trying to effect these exercises that require of her a sort of attention that she has not hitherto known and without which she will make errors. It is precisely because of these errors that she will make that she will have a chance to realize that she does not know what it means to be really concentrated.
