This page did help a little with undestanding the mantras associated with the chakra petals, but it doesn't tell you how to pronounce the petals. Is there anywhere where I can understand this more? I'm also interested in the siddhis associated with the petals as I was sure they had a more deeper meaning.
I've tried looking up ways of pronouncing the sanskrit letters and alphabet but haven't found anything to help me.
