Symbol Meaning

After starting my yoga practice, I became intrigued with the chakras and the meaning of the symbols. For example, the 7th chakra uses the Om symbol as shown below (all credits for images go to respective sources).


Another image of the 7th chakra contains additional symbols that from my very limited research represent petals of the lotus flower and consonants in Sanskrit language.


There is a variation in the symbol regarding Element 4 in the following diagram that further explains the meaning of the symbols. The first image contains a diamond shape. The second image contains a circular shape.


Now, focus for a moment on the 4th chakra. Below are 3 images each of which contains a variation.




That third image of the 4th chakra looks the best to me. If I were to modify that image by replacing the circle with a diamond, would the meaning change? I found the following chart this morning on Sanskrit consonance.


The innermost symbol matches “ya” consonant and would then have a diamond instead of a circle on the image I create. What would be your interpretation of that resultant image?
