Verse
काङ्क्षन्तः कर्मणां सिद्धिं यजन्त इह देवताः ।क्षिप्रं हि मानुषे लोके सिद्धिर्भवति कर्मजा ॥
kāṅkṣantaḥ karmaṇāṃ siddhiṃ yajanta iha devatāḥkṣipraṃ hi mānuṣe loke siddhirbhavati karmajā
They who desire the fulfilment of their works on earth sacrifice to the gods (various forms and personalities of the one Godhead); because the fulfilment that is born of works (of works without knowledge) is very swift and easy in the human world.
Gītā 4·12
