Chakras like Kulakul, Akathah,Akadam and so on.

[yogi]

This chakras for selection friendly mantras(mitra) and and avoid hostile mantras(shatru). I tried to identify my friendly mantra, and came to misunderstanding, because the same pattern, the mantra turns friendly, but by same the others, the same mantra turns hostile.
How to be, and how these patterns are really important?
