The mantra known as "Krsna" is extremely powerful. Same with ram. RAUM was originally derived from Ram. These are deities which have extremely powerful attributes if utilized properly. If the au formula is added it becomes very powerful in certain instances.The trick is to read particular books and not websites for Hindu mantras. Alain danelious work,David frawleys work, etc etc and our high priests sermons are goldmines. You need to have a perspective mind to figure out which one is a word of power. Always meditating on the feeling of the mantra after vibration gives you better understanding about it and the universal principles/attributes it is derived from. Vibrate krsna 108 times and see what kind of feeling you get. Kh is glutural remember. R has to be rolled. The same formula used on the joyofsatan is supposed to be used everywhere. Remember Hindu mantras are extremely long and unnecessary unless youre doing some kind of deity summoning. Just derive the root word and vibrate that. Mantra yoga and primal sound is a nice place to start. In any sect of yoga to attain divination or great power you need a demon to guide you. You should always ask your gd to tell you how to study these things and take out the important stuff and how best to utilize it.
