The breath is so powerful. How does it work in connecting us to the subtle dimension?

Question - Gurudev, the breath is so powerful. How does it work in connecting us to the subtle dimension?

Gurudev Sri Sri - My dear, in the subtle you are already connected. The breath only makes you realise that you are connected. Your mind is always outside and it does not come back to itself, so the breath is the first step in bringing the outgoing mind inward. It is the doorway or the pathway, and meditation keeps the mind in the inner chamber.
