This philosophy is to some extent similar to the vedic philosophy explained by Lord Krishna in ‘Bhagwat Geeta’, where Lord Krishna describes qualities of a perfect human as ‘Stithpragya’. Geeta has used the example of Tortoise to describe a balanced human-being as one who has gained full control over his organs like a Tortoise does which whenever needed, opens its limbs of body and when not needed, closes them.
There is a very serious debate and difference of opinion between religious philosophers and historians as to whether Jains are of Hindu stock and whether their religion is more ancient than the vedic religion of Hindus. Spiritual philosophy of Hindus and Jains in many respect is different but the quintessence of the spiritual thought of both the religions seems to be the same. The influence of Hindu vedic religion is quite apparent in the custom, style of living, belief and faith of Jains. Jains do not worship images or idols of Gods but worship their Tirathankars meaning their ideal personalities who have attained human perfection and excellence by a process of self-improvement. The literal meaning of the word ‘Jain’ is one who has attained ‘victory’.
It signifies a person who has attained victory over himself by the process of self-purification. ‘Jain’ is a religious devout who is continuously striving to gain control over his desires, senses and organs to ultimately become master of his own self.
