The Siddhars did not seek death as a solution for their objective . For that they neglected their family and society and attained a good state in their subconsciousness and reached God. They lived in forests, mountains and caves where there was no human movement and they studied the medicinal properties of various herbs to protect themselves from harm for their lives and bodies. In addition to their exploits, they also wrote medical notes on the trails to benefit other people who lived outside the social boundaries they despised. It was the Siddhars who sang about the impermanence of the human body and addressed the Nemerkummizli wound, they also engaged in medical research to maintain the body. It was these medical researches and activities of Siddhars that evolved into Siddha medicine. It was the reason for the origin and development of Siddha medicine. It can be said that it is the spirit of life that is hidden in the subconscious of Siddhars. It was the feeling that created the need to maintain their body and life which made them search for the medicinal properties of herbs. Siddhars felt that this search and research should not stop with their use but should be helpful for social use. It was the indomitable spirit of life in the subconscious mind of the Siddhars that gave the world the superior medical system of Siddha medicine. Although the Siddhars continued to emphasize impermanence in their thought expressions, they were clearly aware of the power of the human body and the power of the soul: "When I nurtured the body, I nurtured the soul".Thirumool's lines are proof of this.
