श्रेयान्स्वधर्मो विगुणः परधर्मात्स्वनुष्ठितात्।
स्वभावनियतं कर्म कुर्वन्नाप्नोति किल्बिषम्।।१८.४७।।

Meaning

It is better to do one's own duty, however defective it may be, than to follow the duty of another, however well one may perform it. He who does his duty as his own nature reveals it, never commits a sin.

Hindi Meaning

अच्छी तरहसे अनुष्ठान किये हुए परधर्मसे गुणरहित अपना धर्म श्रेष्ठ है। कारण कि स्वभावसे नियत किये हुए स्वधर्मरूप कर्मको करता हुआ मनुष्य पापको प्राप्त नहीं होता।
