Aloha Bryan,

I forget what the yogic term for that syndrom is, but it involves a rush of prana through the higher centers which the body is not yet able to streamline through and so your spirit checks out for a moment, It happens often in kundalini yoga circles. Although slightly intense on the nervous system it gives you the opportunity to really perceive yourself from beyond. As you continue practicing yoga and breath, it will happen less and less frequently as your vibration and level of awareness approach that state that your spirit jumps out to reach.

may your steps along the yogic journey be guided with ease and grace
