Bhagavad Gita · Chapter 3: The Path of Action
Bhagavad Gita 3.11
देवान्भावयतानेन ते देवा भावयन्तु वः ।
परस्परं भावयन्तः श्रेयः परमवाप्स्यथ ॥
devānbhāvayatānena te devā bhāvayantu vaḥ | parasparaṃ bhāvayantaḥ śreyaḥ paramavāpsyatha ||
"Nourish the gods with this, and let the gods nourish you. Nourishing one another, you will attain the highest good."
Modern context
'Nourishing one another, you will reach the highest good.' The gods here stand for the powers that sustain life: sun, rain, earth, wind. The relationship is two-way: we are kept alive by forces we did not make, and we have a part in sustaining them. Wellbeing is shared or it does not last.
