I believe the answer to the question about the 1st wave is not quite the same as the 2nd.

In the first those that were at the level that so, so many find themselves today just was not the case.

So those that were Ascending did so as part of the plan. They came here and showed folks what this life has as possibilities and they left in many described ways to leave a pattern to follow.

The first level of spiritual organization that would allow a wave would have been in 1987.
