In your TM course, you were probably surprised by the simplicity and effortlessness of the practice, which results from the nature of the mind to seek happiness. It is therefore spontaneously drawn into the bliss of silence, like a river flowing towards the ocean. We just go with that flow. We don’t look for silence (that would be counter-productive) we only have to ‘let it be’ (be innocent) and silence naturally overtakes. This is known as the process of Yoga or integration of life.
