दैवाद्यन्तं तदीहेत पित्र्याद्यन्तं न तद् भवेत् । पित्र्याद्यन्तं त्वीहमानः क्षिप्रं नश्यति सान्वयः ॥ २०५ ॥

sanskrit

Let him make (the Sraddha) begin and end with (a rite) in honour of the gods; it shall not begin and end with a (rite) to the manes; for he who makes it begin and end with a (rite) in honour of the manes, soon perishes together with his progeny.
