The bija mantras all rhyme with "Mom" except for "OM" (rhymes like home), and "All" (rhymes with call).
They are:
Lam
Vam
Ram
Yam
Ham
Om
All
It is important to chant these in the order listed.
1.) Take a deep breath and begin chanting the bij mantras, one after the other, until you finish with "All".
2.) Take a second deep breath and start chanting again from the beginning.
3.) Repeat this process at least ten times.
