Benefits of chanting Vishnu Sahasranamam
Approximately 72000 nadis are found in human body. Each namam in the Vishnu Sahasranamam corresponds to one verse of the Brihati sahasra (part of Vedas) that has 36 aksharams(letters)which is the form of Lord Vishnu. Each akshara is again composed of a swara(eg: a,u) and a vyanjana(na,ma) and there a total of 1000 mantras. So it adds up to 36000 swaras and 36000 vyanjanas which correspond to the 36000 (360 days ×100 years) and 36000 (360 nights ×100 years) of a complete human life span of 100 years i.e., 72000 days and nights and (sathamanam bhavathi). The human body is kept alive by a life-force which is pulsing through each and every cell and this is done through the 72000 nadis(energy lines) as per the ancient siddhars. There are 36000 nadis on the right and 36000 on the left side of the body. When we chant the Vishnu Sahasranamam all these nadis are cleansed and energized which helps in uplifting our mind and body.
