Watch your breath , then stay in the middle without perceiving any thoughts coming from all directions.
Once you enter in non perceiving mode then grace or pure energy will start flowing in you from your forehead or from back of your head. Stay in it for 15 minutes.
This energy will accumulate gradually in your body over a period of time in practice . Once accumulation completely fill you with cosmic energy then it will explode out of you making you one with the whole creation.
