The third day was packed with setting the vowels and consonants together. It is structured quite mathematically, but it is kind of easy to forget the simple rules when you are in the middle of it.
Moritz Ulrich said just practice the letters with chanting and we can try to write every letter according to where it is in the palate, from 1-5 place.
There first two rows of consonants are soft letters and then two rows of hard letters. Every other row is alpaprana and mahaprana.
