What is the best moon phase to use and which retrograde to avoid for a sri yantra?
 

Which moon phase should I use a Sri Yantra? And which retrograde to avoid? Mercury retrograde is coming on September 27, 2021. I am also a thinking of using a bay leaf on a Sri Yantra to manifest some stuff like weight loss and health. I tried google, but all search links point to something else unrelated.

Your help is appreciated.
