सिद्धान्नाद् वैश्वदेवं वै कुर्यादगनौ यथाविधि,सिद्ध अन्न (तैयार हुई रसोई) मेंसे अन्न लेकर उसके द्वारा विधिपूर्वक बलिवैश्वदेव कर्म करना चाहिये
siddhān nād vaiśvadevaṃ vai kuryād agnau yathāvidhi
Vāyu said: “From food that has already been cooked and is ready to be served, one should take a portion and, in the sacred fire, perform the Vaiśvadeva offering in the prescribed manner.” The teaching emphasizes that daily household life becomes dharmic when one first dedicates a share of one’s sustenance to the divine and to all beings, rather than consuming it solely for oneself.
वायुदेव उवाच
Before eating, a householder should consecrate a portion of the cooked meal through the prescribed Vaiśvadeva offering, cultivating gratitude, self-restraint, and the ethic of sharing one’s sustenance with the divine order and all beings.
Vāyu is instructing on proper daily conduct (ācāra) for householders, specifying that the Vaiśvadeva rite should be performed using a portion taken from the already-prepared food and offered into the sacred fire according to rule.
