Regarding setting up a meditation program

[Exar]

As it is, I really want to set one up, and make it one I can easily follow. That part is up to me, however, I have some questions:

1) Are there hour+day combinations that cancel each other out, like planetary retrogrades?
2) I'll look over it again, but how is the "Empowering Aura" meditation different from empowering the chakra points? Does the Aura just let the chakra flow into the light body, then into the aura?

I have more, but 2 at a time is enough.

Thanks in advance.
