Hi, I have read that for a mantra to be effective one must repeat it with full concentration and with a specific rythmic vibration. Each mantra has a specific rythmic vibration. Can anyone tell me how find out the rythmic vibration for a specific mantra; a website or something. Also mantras have intonations, can someone tell me where I can learn these intonations. Lastly I would like to obtain some sanskrit mantras for chamunda, shiva and his forms and for maa Kateri:smash:

Hi out there, I am a newbie here and I registered to this website to find out more about hinduism. Well what I want to know are the benefits of worshipping mahabhairav and the different mantras for this diety and its different purposes and I would also like to know the benefits of worshipping Maa Kateri and her mantras. Thank you.
