There comes no point in meditation when you can say, "Now it is the full stop." There is no such thing as a full stop, because you are carrying the whole sky within your heart, a whole universe in your being.
Meditation is trying to find the ultimate limit. You always feel that you are coming closer to it; you are always coming closer, and closer, and closer. It is always coming closer, but you never reach it, because the limit that you seek is just like the horizon - you can go towards the horizon, thinking that it looks only a few miles away at the most, where the earth and the sky are meeting, but they do not meet anywhere. So as you go on, your horizon also goes on receding; you will never reach to the horizon. What is true about the inner consciousness is also true about the outer space.
