In Jainism, the phrase "dharmi son of adharmi father" is often used to illustrate the principle that each individual is responsible for their own karma, regardless of their family background. According to Jain philosophy, "dharmi" means someone who follows the path of righteousness (dharma), while "adharmi" refers to someone who follows the path of unrighteousness (adharma).

The concept is sometimes exemplified with stories from Jain scriptures where a virtuous son (dharmi) is born to a father who is not righteous (adharmi), or vice versa. This emphasizes that spiritual progress and liberation (moksha) depend on one's own actions (karma), and not on one's lineage or family. Each soul is independent and must strive for its own purification, regardless of family circumstances.

Thus, in Jainism, a "dharmi son of adharmi father" signifies that righteousness is a personal choice and responsibility, and one can attain spiritual purity even if born in a family where others are not following the path of dharma.
