Answer: No one can say how much time we have left until Gmar Tikkun (the end of correction). This was spoken of much by the prophets who spoke about it in hidden allusions. This means that they also didn’t know when it would happen because it relates to our free will. Baal HaSulam thought that Gmar Tikkun would come tomorrow if not today since everything is ready for it from Above!
We also think that it will happen soon. We can base our belief on what is happening in the world today, although no one knows anything for sure. It says that the correction will take 6,000 years, which means that there are 228 years left. But is it really during this length of time that we have to reach Gmar Tikkun, in a good way or in a bad way?
In a good way we can reach correction tomorrow, or even today. There are no limits here. If we want to be corrected, our desire will immediately summon upon us the influence of the upper field. No special arrangement on the Creator’s part is necessary. Our desire is enough in order to evoke it. We are the masters of the states we find ourselves in.
We cannot know when it will happen, but as we near Gmar Tikkun, after the revelation of the upper world, which is called a spiritual birth, we still feel this world in all the 125 degrees of the spiritual ascent. The moment we reach the general correction and everyone is corrected, there is a connection of all the vessels, of all the individual spiritual desires, then our world disappears, since there is one general vessel for all the desires to receive.
When its last particle moves on to bestowal, there isn’t one desire left that is not corrected and in order to bestow. Therefore, the feeling of this world that exists only within the egoistic desire without a Masach (screen) disappears! And only the upper world remains!
Since all the desires are connected, all the worlds unite and become one general upper world, in the level of Ein Sof (Infinity). So by attaining Gmar Tikkun together with the whole world, you cease to feel this world. You will not need it! And besides, you will have no vessels to perceive it, since you have corrected your last egoistic desire. Then this reality will disappear from your feeling.
