The Sound of Silence
There is an unbroken sound playing inside every human being. It rings continuously for 24 hours from birth to death. This sound can be heard sitting in a quiet place. If it is not heard even in a quiet place, then it can be heard with your ears closed.Some people call it the sound of the Soul. Some consider it a means of meeting the Soul. Some people keep listening to this sound during meditation. People say that listening to this sound, helps the mind to concentrate easily.
I don't know whether anyone has reached near the Soul after hearing this sound? But it is true that this voice is playing continuously inside and listening to it calms the mind.
