<human>:  What are the best methods for breathing deeply and controlling one's breathing for meditation?
<bot>: The best methods for breathing deeply and controlling one's breathing for meditation include diaphragmatic breathing, box breathing, 4-7-8 breathing, and alternate nostril breathing. Diaphragmatic breathing involves focusing on the breath and placing one hand on the abdomen, allowing it to expand during inhalation and fall when exhaling. Box breathing requires inhaling for a count of four, holding the breath for a second count of four, exhaling for a third count of four, and then holding the breath for the last count of four. 4-7-8 breathing emphasizes a more controlled inhalation, with a four-count inhalation, the counting of seven silently, and an eight-count exhalation. Lastly, alternate nostril breathing, also known as Nadi Shodhana, is where you close off one nostril at a time and inhale through the open nostril and then exhale through the other. This can assist in calming the mind while allowing the breath to become deeper, more even, and more controlled.
