The Siddha system says the human body both the physical and the subtle is made up of 72,000 veins and nerves and 7 vital nerve centres (Chakras) along the route of the spinal cord.
The three important being Sun, Moon and Fire, the 10 vital airs (Prana) and 10 vital nerves (Nadis). Out of the ten vital nerves (Nadis) the first three namely Idakalai (Moon) Pingalai (Sun) and Suzhumunai (Spinal) play an important role in the technique and prolongation of life.
Siddhars maintain that voluntary control of breathing is possible to a certain extent and that it will lead us to porlong our life span. The process of respiration in which oxygen is inhaled into the living cells and carbon-dioxide is exhaled from them is a fundamental phenomenon of life which is universally present in every type of living organism. The respiratory centre that regulates rythmic muscular contractions concerned with breathing is known as Medulla.
Siddhars hold that the subtle air (Prana) begins at the centre of Lalada, passes through the Chitra or Chandra Nadi, jumps into sacral plexus with the sound `ov' and Navel plexus with the sound `av' where from it enters into Idakalai and Pingalai nerves with the sound `Sav' and circles the cerebrum and finally enters into nostrils charging out at a length of 12 inches and with drawing only 8 inches inside at the same time, thus loosing in the process 4 inches. This goes on repeating itself in the act of breathing.
A part of the energy that ought to have entered the body is lost in every process of respiration and thereby the normal life span of 120 years is considerably reduced.
The normal rate of breathing of a modern man may accordingly be calculated upto 61,600 in a day. On account of this, modern man loses much of his energy in excessive breathing and his life span is also considerably reduced.
Siddhars have developed the science of breathing which helps to assimilate the full energy needed by the body for the purpose of living a life free from decay and diseases.
Tirumantram is one of the important works in Tamil dealing with the science of life. It is the outcome of Tirumular's love and desire that mankind should share the fruits of his valuable experience attained during his Yoga supposed to have been practised for three thousand years.
