CHAPTER 4 · VERSE 12
Bhagavad Gita 4.12
काङ्क्षन्तः कर्मणां सिद्धिं यजन्त इह देवताः। क्षिप्रं हि मानुषे लोके सिद्धिर्भवति कर्मजा॥
Those in this world who desire success in fruitive activities worship celestial beings; for success born of work comes quickly in the human realm.
Explains why many seek quick material rewards through rituals rather than enduring spiritual growth.
