The Kundalini Breath Guided Meditation is very helpful for Clearing of the Pain / Pranic / Energy Body & simultaneously silencing the Mental Body (Mind) which also results in a relaxing of the Physical Body. Thus, three of the five bodies of humans directly affected positively & rapidly.  

Kundalini Breath Technique "gives the mind a job" of following the breath & guiding it on a major energy circuit within humans as well as assisting the rapid clearing of Tomasic Energy.  

This reduces or eliminates the placing of our Awareness on wandering muddy thoughts that sensation discomfort usually brings, which can then further distract us & affect our ability to "Remain the Witness", rather than imagining we are the thoughts & sensations, the incorrect belief system for the vast majority of humanity that creates all of our sufferings.  The separate "I" illusion. Identified existence.  

Kundalini Breath Meditation essentially allows us to surrender or acquiesce to the deeper Witnessing State, instead of becoming the discomfort & cycling even more negative mental information & thus strengthening the existing problematic thought patterns.
