Namaste
lunarreikin,
Thank you for the information. I think it will be helpful to me.
As to your questions, I don't think these "rituals cease being as effective", but then I can't speak for all. In this case, I think I was just taken off guard, and did not ground myself prior. Basically, my guard was down. I shall be reminded well in the future, I think.
Blessings to you and yours, always,
Dina
