Is there life after death?

We just read Genesis where it talks about the garden of eden and how man was expelled from it.
It then says that the angels are protecting it with a flaming sword that revolves. See Genesis 3:24.
According to Rabbi Michael Bernstein, MD in his book, Windows to the Soul, at page 37-38, he says that the phrase represents the pathway for the souls to the true existence in the world to come which is really the true life. If you come to think of it, we are here for a very short time. Most of the time, we are not on this planet. Does Dr. Michael Bernstein make any sense ? Is there any back up to what he is saying? Based on Gematria, the answer is a chillingly yes. The above phrase, v'ais lahat hacherev hamishapeches equals 1616. Another phrase with same number can be found in Psalms 27:13, where it says, lulay he'emanti liros bitoov Hashem, b'eretz hachaim, or "Had I not trusted in that I would see the goodness of Hashem in the land of life."  The super commentator, Rashi, says that it refers to the eternal world of the world to come, as noted in Talmud Berachos 4a. Gematria indeed confirms the insight of Dr. Michael Bernstein.
