Just take the practice and try it out, and do it, and do it, and do it, and strengthen it, and deepen those grooves of the mind. And somewhere, someday, sometime when you are in meditation, you feel as though all the physical realities, limitations of the universe, and your own personality dropped off for a moment. It is as though you had touched the fringes of infinity in a state of absolute tranquility. And when that happens to you, then you decide whether something beyond this body exists or does not exist. So this is a practice system.
Meditation is a state of mind which is free of conflicts.
Now what is meditation. For a complete beginner it is very difficult to define, until you have experienced it. How would you, having experienced just this one level, just this two or three or four days of practice, how would you, sir, define meditation. You see, you gave your definition from your experience. No, you experience it, and out of that experience, you develop your philosophy and your terminology, and you define it.
