Concerning Spiritual Cleansing rituals

You don't need to worry about the moon phase for Ritual's. I'm relatively sure that a HP said you can do them even when the moon is void. Just do as many as you can, but remember, this isn't some grand competition. If you can get one done a day, that's fine. It's better than none. The more, the better. HAIL SATAN!!!GOT MIT UNS!

Newbie here,  
Extreme wealth of knowledge here on JoS and the groups and appreciative of those who compiled all this together, so I hope this isn't a redundant question, but on the Spiritual Cleansing rituals should we be mindful of the moon phases?  
Since this is against an enemy I assumed a waning moon phase would be more powerful but should we avoid during waxing or does it even matter?  I wasn't sure if this type of ritual was different from others... but I also don't really know what the heck im talking about so,  i decided to ask.   Thanks

Yes you know what you're talking about.

No, the moon phases don't matter for the Spiritual Cleansing rituals. Because they are something collective that was started at the right time.

What really matters is when a ritual is started, and that's what differs the Spiritual Cleansing rituals from other rituals. Individual rituals are often done only once. Spiritual Cleansing rituals are collectively repeated by many Zevism, and it only matters when the first time done by the first person was done. Then the following repetitions can be done at any time.

Hope that's clear enough

Hail Satan!

Do them anytime. New ones are coming at the end of the month.
