We Hindus don't just consider it as breathing, our world view is different. Breathing techniques in India are called Pranayama which means controlling prana.
This is an excerpt from chapter-3 of Raja yoga by Swami Vivekananda.
Pranayama is not as may think, something about breath. Breath indeed has very little to do with it if anything. Breathing is only one of the many exercises through which we get to the real Pranayama. Pranayama means the control of Prana. According to the philosophers of India the whole universe is composed of two materials, one of which they call Akasha, It is the omnipresent, all-penetrating existence. Everything that has form, everything that is the result of combination, is evolved out of this Akasha. It is the Akasha that becomes the air, that becomes the liquids, that becomes the solids; it is the Akasha that becomes the sun, the earth, the moon, the stars, the comets; it is the Akasha that becomes the human body, the animal body, the plants every form that we see, everything that can be sensed, everything that exists. It cannot be perceived; it is so subtle that it is beyond all ordinary perception; it can only be seen when it has become gross, has taken form. At the beginning of creation there is only this Ākāsha. At the end of the cycle the solids, the liquids, and the gases all melt into the Akasha again, and the next creation similarly proceeds out of this Akāsha.
By what power is this Akasha manufactured into this universe? By the power of Prāna. Just as Akasha is the infinite, omnipresent material of this universe, so is this Prāna the infinite, omnipresent manifesting power of this universe. At the beginning and at the end of a cycle everything becomes Akāsha, and all the forces that are in the universe resolve back into the Prāna; in the next cycle, out of this Prāna is evolved everything that we call energy, everything that we call force. It is the Prāna that is manifesting as motion; it is the Prāna that is manifesting as gravitation, as magnetism. It is the Prāna that is manifesting as the actions of the body, as the nerve currents, as thought force. From thought down to the lowest force, everything is but the manifestation of Prāna. The sum total of all forces in the universe, mental or physical, when resolved back to their original state, is called Prana.
"When there was neither aught nor naught when darkness was covering darkness, what existed then? That Akäsha existed without motion." The physical motion of the Präna was stopped, but it existed all the same.
At the end of a cycle the energies now displayed in the universe quiet down and become potential. At the beginning of the next to cycle they start up, strike upon the Akäsha, and out of the Akāsha evolve these various forms, and as the Ākāsha changes, this Prana changes also into all these manifestations of energy. The knowledge and control of this Prāna is really what is meant by Pranayama.
> Those classes are all about conformity. It's about learning how to play the game of life and not going against the grain. "smart students" learn to read their teachers and know how to feedback the expected answers even if they don't agree or believe in it. A lesson that's very much needed in life.
> A lot have not learned this lesson and this is why many of us on this site still marvel at the bullshit companies raising millions and wondering HTF! Because those "smart founders" learned how to feed BS that their audience expected back to them.
> I learned this lesson when I took humanities, it was so stupid, but I knew exactly what the teacher wanted to hear when we studied architectures & paintings. It was all subjective and her own opinion. I fed her back her crap and I passed the class.
> If you haven't learned this yet, it's not too late. The world is full on chicken shit.

Telling something even though you don't believe in it for personal gain is called cunningness.
I see many people misunderstand smartness with cunningness, people who are smart can be cunning as well but they chose not to.
