A question I received: If there is no time in spirituality, then why is it written that correction occurs over a period of six thousand years?
My Answer: Baal HaSulam explains the meaning of “6,000 years” in “A Speech for the Completion of The Zohar,” “Introduction to The Book of Zohar,” as well as other articles. “6,000 years” are the VAK of Zeir Anpin, which need to be realized in relation to Malchut.
When Malchut, the seventh Sefira, reveals all these six qualities, called “6,000 years,” inside itself, it is called the “seventh day,” “Sabbath,” or the “seventh millennium.” Only then Malchut becomes filled for the sake of bestowal.
Therefore, these qualities are called “6,000 years.” Year (Shana) comes from the word “to change” (Shone). We need to experience these degrees one after the other. On one hand, we’re not talking about years in our world. On the other, if we don’t hasten time, then in accordance with the connection of root and branch, the perception of time in our world will comply with its root and the process of correction will actually end in six thousand years.
However, we can change the length and the essence of six thousand years; we can shorten and compress them. Nevertheless, they’ll be called “6,000 years” because we do not cut off degrees, yet according to corporeal time, it will be less.
