I try to meditate every night, but now I'm getting confused. I'm not sure if Mantra and Mudra are the same thing, but how are they really used? For example, if I used Judo as my Mantra, would I chant Judo! Judo! Judo! but quietly. (you know what I mean-- what you do when you chant someone's name over and over) I'm a little confused and overwhelmed here with the stylistic differences and lack of a mainstream way of meditation. Help Me!!!!
