Namaste,

I'm listening to the Foundational Shaivism Lectures right now.

On my studies I looked for origin of the Matrika. I've found that the Chakra are really about them and the deities. Different schools might vary sometimes in the associations.

Now I that understand this it makes learning the Matrika Visualization meaningful.

Also the way I learn languages is I need to write and make the sound associated with it.

I found a web page based based app that is missing one vowel out of the 51 phonemes. Otherwise it is helping enormously.

Here is the link
