Śrīmad-Bhāgavatam · Text 11.18.7
Who is speaking and story frame
वन्यैश्चरुपुरोडाशैर्निर्वपेत् कालचोदितान् ।
न तु श्रौतेन पशुना मां यजेत वनाश्रमी ॥ ७ ॥
vanyaiś caru-puroḍāśair
nirvapet kāla-coditān
na tu śrautena paśunā
māṁ yajeta vanāśramī
One who has accepted the vānaprastha order of life should perform seasonal sacrifices by offering oblations of caru and sacrificial cakes prepared from rice and other grains found in the forest. The vānaprastha, however, may never offer animal sacrifices to Me, even those sacrifices mentioned in the Vedas.
