Noise is of course "External" while with practice one can "Go inside" and find the Silence. One method is through Meditation, whereby you can achieve a state of removing the outward sounds and Noise of living by eliminating thoughts and instead gain the Inner quite which is always present but we are unable to enjoy as a result of out constant mind ramblings. Yes, it takes some practice but anyone can achieve the Silence. Once there -- inside -- then the senses that we use to hear external sounds and sights diminish. Try sitting comfortably with eyes closed and pay no attention to all the thoughts that will flood the mind and gradually you will find the inner quite and experience inner sounds and light. No need to practice any breath control or anything else. Just Still the body with eyes closed for even a few minutes and you will be able to get a glimpse of the Inner Experience. This is is what the Monks showed practicing a way of life in the Youtube video posted above by DealMaker. It is difficult for our rogue mind (Some Call it the "Monkey Mind") to be stilled sufficiently to hear the inner sounds which are always present but blurred out by our egos and senses. BTW, quantum physics supports the science of how, although we believe everything is solid (as in a table) under a powerful electron microscope we are able to detect the truth that everything is in motion (particles and electrons make up the object that appears to be solid like a rock or table. As you know sound is Vibration. Check this link out:
It is the sounds of the universe that demonstrates the fact that everything is in motion. Without vibrations (which in religious beliefs is sometimes called the Spirit, or the Holy Ghost of the Trinity or in other religions the "Word") then the Universe would not exist and be sustained. The markets are also in motion. Cyclical and vibratory. Detect that and your trading will improve.
This may post may be characterized by some as ridiculous -- However, if you are a Quantum Physicist or Rocket Scientist you will embrace it and not scoff.
Careful in searching for Meditation Instruction on Google -- as in most things, there is plenty of false Gurus and Peddlers.
