==Concentration to Open to Higher Consciousness==
''Is it possible to distinguish the moment when one attains perfect concentration from the moment when, starting from this concentration, one opens oneself to the universal Energy?''
Yes. You concentrate on something or simply you gather yourself together as much as is possible for you and when you attain a kind of perfection in concentration, if you can sustain this perfection for a sufficiently long time, then a door opens and you pass beyond the limit of your ordinary consciousness—you enter into a deeper and higher knowledge. Or you go within. Then you may experience a kind of dazzling light, an inner wonder, a beatitude, a complete knowledge, a total silence. There are, of course, many possibilities but the phenomenon is always the same.
To have this experience all depends upon your capacity to maintain your concentration sufficiently long at its highest point of perfection.
''To have this experience is it necessary to concentrate every time?''
In the beginning, yes, for you have not the capacity to keep what you have acquired, to maintain your concentration at its maximum—you slip back and lose even the memory of the experience you have had. But if you once follow a path, it is easier to follow the same path a second time and so on. The second concentration is therefore easier than the first one. You must persevere in your concentration till you come to the point when you no longer lose the inner contact.
From that time onward you must remain in this inner and higher consciousness from where you can do everything. You see your body and the material world and you know what is to be done and how to do it. That is the first aim of concentration, but naturally not the last.
