Hello
I was curious if i chosed to chant mantras mentaly in a silent way,- due to privacy issues- would this make them weaker than loud chanted mantras ??? Do i need to increase the number of reps in this case ???
However i use the mantra aum 9 times for void meditation but -you know- i cant chant aloud because i live in muslim environment and if they knew about me, they will accuse me of being insane.
Thank you
