CHĀNDOGYA UPANISHAD · 3.6.1

तद् यत् प्रथमम् अमृतं तद् वसव उपजीवन्त्य् अग्निना मुखेन ।
न वै देवा अश्नन्ति न पिबन्ति ।
एतद् एवामृतं दृष्ट्वा तृप्यन्ति ॥

tad yat prathamam amṛtaṃ tad vasava upajīvanty agninā mukhena ।
na vai devā aśnanti na pibanti ।
etad evāmṛtaṃ dṛṣṭvā tṛpyanti ॥

On the first of these nectars (the red light, which represents fame, glory of countenance, vigour, strength, health) the Vasus live, with Agni at their head. True, the Devas do not eat or drink, but they enjoy by seeing the nectar.
