The second method to ENTER is : Kuan Yin's 耳根法门

This method is using the EAR Faculty to listen and to ENTER IN. First of all....you will need to sit in a quiet corner of your house and meditate. 

Simply breath IN and then breath OUT. Then when you feel that you are calm enough....then do this : Ask : Who is the one who is listening to the sound of air con in the room ? or any other sound that you are listening now. Keep doing this all the time, every time you are doing your meditation.

You have to do this until you can feel a pulsation at the space where the third eye is. There is some movement. Then keep doing it until you experience a crack here and there around the head or face. You will need to continue doing this until all are cracked up and this may take a few years.
