Dirgha pranayama, yogic breathing, nadi shodhana, bhramari - all these help to bring a balance in the body and calm the mind. Hence, you feel more relaxed, centered and happy.

I would say both. It is a great way to reduce the thoughts, calm the mind and bring one-pointedness. Meditation also takes one ahead in the spiritual journey and I believe that we all are spirits on a spiritual journey.

Closing the eyes. Then breath awareness.
