यज्ञार्थं पशुहिंसा या सा स्वर्ग्या नेतरा क्वचित् । त्यजेत्पर्युषितं सर्वमखंडस्नेह वर्जितम्
yajñārthaṃ paśuhiṃsā yā sā svargyā netarā kvacit | tyajetparyuṣitaṃ sarvamakhaṃḍasneha varjitam
The killing of an animal for the sake of sacrifice (yajña) is said to lead to heaven; other killing is never so. One should abandon all stale food, and anything lacking unbroken, wholesome richness (deprived of proper fat).
Skanda
Tirtha: Kāśī
Type: kshetra
Scene: A small yajña scene contrasted with a hunter: on one side a regulated sacrificial altar with priests; on the other, ordinary killing shown as shadowy and rejected; alongside, a pilgrim discards stale food and chooses fresh sattvika fare.
Dharma distinguishes sanctioned sacrificial context from ordinary violence, and also insists on purity through fresh, proper food.
Kāśī is the implied sacred environment where refined dharma—both ethical and ritual—is to be observed.
A doctrinal rule about yajña-context violence, plus a practical rule to avoid stale/kept food and improperly prepared foods.
