You can create mantras also. I have created mantras myself. You're just reading books, that's it. If you play cricket, I can see that. By learning forward defense, back defense, by reading a sweep shot, can you play a game? No. So when you were a young boy, did you go to those books or you just start playing it? So it is not about books. Books are only referring to some experiences. In Hinduism, they are saying that these are matrikas or these are warand malas. So there are initially six warand malas, which are basically the Lordiva's Shakti, reside in all these six. Because I use Hebrew words to check how these energies work. You can experiment, you can do, but you can only do these things. You become a master of it. Then this book doesn't matter.
