After making a mixture, the feet of the cow should be washed with the following mantra.
क्षीरोदार्णवसम्भूते सुरासुरनमस्कृते ।
सर्वदेवमये मातर्गृहाणार्घ्य नमो नमः ॥

After the worship, the cow should be offered this prayer by feeding large pieces of urad-
“सुरभि त्वं जगन्मातर्देवी विष्णुपदे स्थिता ।
सर्वदेवमये ग्रासं मया दत्तमिमं ग्रस ॥
ततः सर्वमये देवि
मातर्ममाभिलाषितं सफलं कुरू नन्दिनी ॥“
