"Jin Puja se Gopal banaa Raja" is a saying that emphasizes the transformative power of worshipping the Jinas (Tirthankaras) in Jainism. The phrase means "By worshipping the Jinas, even Gopal (an ordinary person) became a king." In Jain tradition, it is believed that true devotion to the Jinas leads to spiritual upliftment, removal of karmas, and progress toward liberation (moksha). The phrase is often used to inspire faith in the efficacy of Jin Puja (worship of the Jinas) and to encourage devotees to engage in such worship with sincerity and devotion.

The story behind this saying is not literally about a historical figure named Gopal, but rather serves as a moral teaching that anyone, regardless of their background or status, can achieve greatness and spiritual elevation through the sincere worship of the Jinas, following their teachings, and observing Jain principles such as ahimsa (non-violence), satya (truth), and aparigraha (non-attachment). This aligns with the Jain belief that liberation is accessible to all, regardless of social or economic status, if one follows the path shown by the Tirthankaras.

Thus, "Jin Puja se Gopal banaa Raja" is a motivational proverb in Jainism, illustrating the potential for transformation and upliftment through devotion and right conduct.
