sounds of bird chirping , noise from outside traffic in other words I listen to whatever is happening around me and allow my mind to think but I dont pay any attention to thoughts , I try not to get involve with them, I let them be, it’s very difficult but sometimes I can achieve no mind or stillness within me but lasts for few seconds and again I catch myself thinking and at times I try to watch my breathing also.

is this the correct form of zen meditation.
