Mantra is another object of meditation. Mantras are chanting energy. The purpose is to focus the mind. (Man=the mind Tranam=protect)
mananāt trāyate iti mantraḥ = that which binds your mind in one place
SoHam I am that.
Tatvamasi > know thyself > I am that.
Inhale So Exhale Ham, when this becomes a repetition without awareness change it : Inhale Ham Exhale So.
There are three ways to practice mantras :
- Vaikhari : To pronounce the mantra loudly.
- Upamshu : Slowly pronounce, only lip like a whispering tone.
- Manas : No sound. Mentally.
The mantra reveals the knowledge by itself.
