May one learn how to breathe from the diaphragm (Buddha Belly Breathing) holistically throughout all of their activities and if so how exactly? Peace, Divine Love, and Blessings to All.  I recently began to research meditative/breathing for the Solar Plexus.  I was instructed that the &quot;normal breathing&quot; done in the west is not the right/true way that we are supposed to be breathing but instead we should do it from the diaphragm (liken unto babies).  During my research, I came across Belly Breathing/Diaphragmatic Breathing which I came to find out is &quot;Buddha Belly Breathing&quot; (please forgive me if I come across as ignorant not knowing the true terminology and cultural linguistics).
The very little I have done so far has been amazing but extremely difficult.  Inhaling while expanding the stomach (and vice versa) took a lot of concentration while simultaneously trying to keep an erect posture with square shoulders (all while trying to be loose) was/is full of challenges. It made me consider and realize, one how bad my posture is (sad face) and two is it possible to continuously and consistently do this form of breathing throughout the entire day and in all activities?  I understand that meditation is about going inwardly, so I know I must take that journey and do the inner work but I pose this question asking if there are people who have done it, are doing it, and would they kindly share any pointers or guidance about their accomplishment(s).
This question is open to anyone. Feel free to share howsoever you are led to...Thank you.
(As suggested this question was posed on the Hinduism StackExchange as well)
Welcome to the community! Before answering your question, I believe some clarification would be helpful.
As the user Buddhism pointed out, specific breathing exercises are more related to other ascetic practices of ancient India. One important component of the Buddha’s discovery of the path to awakening, is the leaving aside of exercises such as these. What the Buddha taught instead was the mindful watching of the breath, as well as the development of the four establishings of mindfulness.
But leaving that aside, to answer: yes, it is possible to maintain a meditative state throughout the day, and it was something that was actually taught by the Buddha. Though I do not practice to that extent myself (I find that it requires a great deal of mindfulness, which I do not have yet), it was the way the Buddha encouraged his disciples to practice, and it is my understanding that modern monastics are encouraged to practice in this same way as well.
I hope this is helpful, and Metta.
