Chanting God Names - Some Questions (Re-Post)

[Way_Seeker6661]

Greetings. What I need to know of this is:
1) Must it be done for 40 days and nights, as with the Runes?
2) How do I find the number of repetitions for a specific God name?
3) Does this bring up past life karma as the Runes do?
4) How important is it to time the working with the planets and moon phases?

Thanks in advance
