Conduct or activity alone is considered to be enough to secure salvation. Such one-sided religious beliefs are dismissed by the Jaina thinkers. They maintain that all the three must be present together to achieve the purpose. Very often the following analogy is quoted. Salvation implies escape from Samsara which is associated with birth, old age and death.
Every person aims to reach a place which is free from birth an death.
Such a desire is similar to the desire of a sick man to cure himself and attain normal health. Such a desire to be effective, the sick man just have implicit faith in his doctor, whom he consults. Next he must have a clear knowledge of the medicine prescribed by the doctor and thirdly he must take the medicine according to the instructions given by the doctor. Faith in the doctor, knowledge of the medicine, and taking the medicine as prescribed, all these three are necessary to eradicate the sickness and to secure normal health. Similar is the acquisition of spiritual health, which would be secured only by the co-operation of the three items of Right Faith, Right Knowledge and Right Conduct.
