I start to focus on my sound base chakra once again and start to increase my chakra flow, I then start to concentrate on my surrounding and my sound chakra and start to hear a sound which is bouncing of from one object to other, in the beginning the sound is faint so I further concentrate on it to make it more clear, I can now clearly hear the bouncing of sound from one object to other.Good thats the first part of this technique. Now I want you to focus that at the same time focusing sound chakra through your breathing. It takes extreme concentration. As your breathing your sound chakra you should be able to hear sound bouncing off of objects.
