Mantra 1

अथ यत्पञ्चमममृतं तत्साध्या उपजीवन्ति ब्रह्मणा मुखेन न वै देवा अश्नन्ति न पिबन्त्येतदेवामृतं दृष्ट्वा तृप्यन्ति ॥ ३.१०.१ ॥

In plain words

That which is the fifth nectar the Sādhyas live upon, with Brahman for their mouth. The gods do not eat or drink; they are satisfied by merely looking upon this nectar.
