Generally people have no awareness about the role of five senses. As far back as the 1760’s, the famous philosopher Immanuel Kant proposed that our knowledge of the outside world depends on our modes of perception. In order to define what is “extrasensory” we need to define what is “sensory”. Traditionally, there are five senses: sight, smell, taste, touch, and hearing. Each of the senses consists of specialized cells that have receptors for specific stimuli. These cells have links to the nervous system and thus to the brain. Sensing is done at primitive levels in the cells and integrated into sensations in the nervous system. Sight is probably the most developed sense in humans, followed closely by hearing. Here I am focusing some pranayam which all are related with senses and brain.
Sheetli Pranayam; this pranayam is closely associated with taste glands, which are connected to the brain. It hits especially that part of the brain which is interconnected with tongue or taste glands.
Ujjai Pranayam; this pranayam is basically for throat glands or whole throat area (speech), it react that part of the brain which are closely connected with throat.
Anulom-vilom; “by proper practice of pranayama etc, all diseases (mental or physical) are eradicated. Through improper practice all diseases can arise.”
Yogi swatmaram states that alternate nostril breathing purifies the nadis (whole nervous system) within three month. This anulom vilom is one of the best techniques in whole pranayam series. In this pranayam you have to take smell like any perfume. Feel the sensation around internal part of the nostril. It connects to right and left brain.
Tratak; in this meditation let focus on middle part of both eye brow, but try to not blink eyes. This pranayam is for eyes and brain nerves.
Sensation (touch); every pranayam has sensation, while inhaling feel the sensation of skin on breath.
Bhramri Pranayam; this pranayam is especially for listening. And it effect on that part of the brain which is connected from ears.
Brain; through these pranayam the whole brain is covered.
