The silencing of the thought waves of the mind is the true definition of yoga. The postures and the breathing lead you to the point where you can silence the thought wave of the mind, so you can achieve that witness space, that separation between your mind and your true essence, the light within. The mind is your tool, you can train it very well, but it’s not you. This tool is for channeling the kundalini energy, this primal force, which starts at the Muladhara chakra, the base, and winds up to the crown center.
