When the offerings made at Shraddhas are exchanged by the performers with one another, they become Pishacha presents. Such offerings please neither the gods nor the departed Manes, Instead of reaching the other world, they wander about even here like a cow which has lost her calf wandering about within the fold.
यथाग्नौ शान्ते घृतमाजुहोति तन्नैव देवान् न पितृनुपैति। तथा दत्तं नर्तने गायने च यां चानृते दक्षिणामावृणोति॥
