 The "sadhanas" include "simran" (repetition, particularly silent repetition of a "mantra" given at initiation), "dhyan" (concentration, viewing, or contemplation, particularly on the Inner Master), and "bhajan" (listening to the inner sounds of the "Shabd").The mantra is Guru Manter.These are some verbal words that one gets from living masters and chants in mind, not with the mouth.
