काङ् क्षन्त: कर्मणां सिद्धिं यजन्त इह देवता: | क्षिप्रं हि मानुषे लोके सिद्धिर्भवति कर्मजा ॥12॥
kāṅkṣhantaḥ karmaṇāṁ siddhiṁ yajanta iha devatāḥ kṣhipraṁ hi mānuṣhe loke siddhir bhavati karmajā
kāṅkṣhantaḥ—desiring; karmaṇām—material activities; siddhim—success; yajante—worship; iha—in this world; devatāḥ—the celestial gods; kṣhipram—quickly; hi—certainly; mānuṣhe—in human society; loke—within this world; siddhiḥ—rewarding; bhavati—manifest; karma-jā—from material activities
Longing for the fruition of actions (of their rites and duties), they worship the gods here. For, in the human world, success from action comes quickly.
