Marcio: > and the advanced techniques > First you get yourself initiated by a guru and you get the bija mantra. After that you can meditate on the bija, at least twice a day, for about twenty minutes.
Then a little later, you can get some more advanced techniques. It's like a garden. You get the seed-syllable and plant it in your mind. Then, you water the root with deep meditation, and later maybe add a little fertilizer. Just sit quietly and meditate on your bija mantra. Just Be. It's that simple!
