In many of the above mantras, we have used the word M to strenghten the crown chakra and the right brain. I shall give only two mantras here using M.
1) Inhale with = MINGLE
Exhale with = LAGGANM
This mantra particularly helps us to Mingle our Being with super-conciousness with the word gah and then ends at M to bathe the crown chakra with divine Kundalini energy so kindled with the word L.
2) Inhale with = ASSAM
Exhale with = ME-SHE or MISHSHI
This breathing mantra helps us to breathe completely from the legs to the crown of our head.
