The location of the prāṇa is the heart, and it’s function is 21,600 breaths per day. The location of the apāna is the anus, and it’s function is the discard stool and urine. The location of the samāna is the navel, and it’s function is to distribute the digested juices through the nāḍīs, just as a gardener distributes well-water to all parts of the garden. The location of the udāna is the throat, and it’s function to the separate digested food and drunk water, and to project what is seen in a dream. The location of the vyāna is the entire body, and it’s function is to impel all joints of the body.
